It's more-or-less spring now, though it's been feeling like summer recently, so I guess it's time for the annual winter in review post.  At any rate, the Pettit National Ice Center is in the process of melting off the 400 meter oval, so the speed skating season is over. Read more... )

Maybe I'm a little weird, and maybe I hang around with some slightly unusual people, but dang if the mundane world doesn't confuse me sometimes.  I was waiting in line at the grocery store checkout and saw a magazine that on the cover promised tips to shrink your thighs and calves.  Now, I hang around with speed skaters.  We have giant, beautiful thighs.  We're proud of them.  It takes a lot of work to build up quadriceps like these.  Bringing my context to it makes seeing "shrink your thighs" on a magazine cover seem pretty much like seeing "ten steps to a smaller penis" on a magazine cover.  It's just not advice you imagined anyone looking for.

I've been spending a lot of time at the Pettit National Ice center, between the long-track speed skating and the running.  They often have the local "B-96!" radio station playing, and they seem to run "I love the 80s!" segments often.  I guess this is great for us old peoplemasters skaters, enabling us to relive our youth. 

One of the things we have now that we didn't in my youth is Google.  I heard a lot of popular songs (you could hardly avoid that), but if you just randomly hear stuff on the radio you're lucky if you hear what the actual song title is.  Filling my memory are a lot of names of famous bands, titles of songs, and lyrics and tunes, and, for the most part, no connections between them.  There are lots of really famous hits by really well-known bands for which I've certainly heard the song many times and of course I've heard of the band, but I never had any idea they did that.  And even in the case of the few groups I liked and was something of a fan of, all I knew was whatever they chose to print in the cassette tape "J-card" or the little booklet in the CD case.   It's not like there was a Wikipedia entry with additional trivia.

Now and then I hear something I remember from long ago and think to just type it into google and see what appears.  Remember "Tainted Love?"  It had a rather distinct sound, and was a big hit at one time.  Well, it was written by Ed Cobb and recorded by Gloria Jones in 1965.  Before I was born.  The version people my age who grew up in the USA remember was released by Soft Cell in 1981 in the UK.  A year or two later it was a big hit in the US.  Who knew?  I sure didn't.  I mean, it's not like it was a secret, but how would you happen to know?  Yes, the music video is on youtube. I'm so old I remember when MTV played music, but I don't recall seeing this back in the day. It is a glorious example of a weird early music video. The early days of MTV were weirdly wonderful. Everyone had to start producing music videos, but besides not necessarily having much of a budget, back then music videos had just been invented and no one knew what they were supposed to look like yet. Thus, they were fantastic.  ("Tainted Love" might not be much of an actual love song, but in my personal case what it reminds me of is holding hands, with a girl.  A witty and charming and cute girl, as I recall.)

And, speaking of wonderful music videos, I did see back in the day-but only a few times-the one for Chris De Burgh's "Don't Pay the Ferryman."  It's right here. That's truly a fantastic video from back in the day.

I ran in the Icebreaker Indoor half marathon yesterday. It's held at the Pettit National Ice Center running track because, as I always say, if you are holding a running race in Milwaukee in January, you probably want to hold it indoors. This is my third year running the half marathon, and I think it's a great event and I highly recommend it for anyone who enjoys running in circles. I think it's a lot more fun than people think it sounds like. We're all in there as a group, they have music playing and an announcer announcing, you go past the spectators constantly, and you go past the hydration table every 443 meters so you never have to worry about water. Unless you are one of them, you get passed repeatedly by the really fast runners, which is quite impressive to see. It's like they are doing some sort of interval workout, except the interval is 21.1 kilometers. And many of them are coming back the next day for 42.2km. If you aren't among the slowest then you in turn get to lap other runners, which makes it really feel like some sort of race. It takes about two laps for the field to spread out and start to sort out by speed, and after that for the most part it's not much problem to pass and be passed.

My time this year was 1:46:16, 64 seconds faster than my previous best half marathon, which was last year's Icebreaker. Best of all, nothing in particular ever hurt. There are ups and downs, times I felt good, times I felt really tired and just plain beat, but no foot blisters, weird knee pains, muscle cramps, or any other sort of specific injuries or pains.

I started long track speed skating because of the Icebreaker run. I signed up for the half marathon back in the fall of 2010 and did quite a bit of running in the Pettit center in preparation, mostly after work during the time the speed skating sessions are running. I saw the speed skaters and thought I wanted to try that, and now I'm out on the oval regularly. I thought it might be fun to do some speed skating during the running of the marathon today, and it was. I found out that I can match the speed of the marathon winner, but only if I have speed skates on. A few of the runners chatted briefly while I was gliding around the outside of the ice, and the skaters thought it was interesting that I'm also a runner and had run the half the previous day.

After a little more than an hour of mostly easy skating I went to Lapham Peak to ski. It was cloudy and a bit foggy today, but it turned out to be a really beautiful day at the park, with a frost effect coating trees and pine needles in parts of the park with ice crystals. After all the other activity I was going to take it slow, and it really was a pretty day to just ski around (and take some photos) and enjoy the place without athlete-ing around trying to achieve a fast time.

I wonder if other people's experiences are similar to mine, so I thought I'd write about this and ask if anyone has any comments on how this works for them.

Lying in bed at night, settled and still, the most prominent sensation (given that there aren't many) is the beating of my heart, and the sensation of my pulse around my body.  I always find the sensation of the pulse interesting.  It's not simultaneous throughout the body and when you start pondering the actual hydraulic delay from heart to feet and then the nerve delay from feet to brain and then contemplate how the brain heavily processes our perceptions of time and simultaneity I can lie there thinking about it for a long time.  These are the things on my mind in the evening.

After a day in which I've done some hard exercise, especially exercise late in the day, my resting heart rate will be elevated, as expected.  Sometimes elevated quite a bit, and that becomes an obvious sensation.  I tend to feel restless even though tired after a hard day, and I always wonder how much of that is the obvious racing heart sensation and how much is from other aspects of post-exercise physiology.  I suspect the brain itself is still a bit revved up, and the muscles even if not really achy still feel used.

My morning lying-down heart rate is typically around 50 or low 50s, the evening lying-down rate if I haven't done much that day maybe mid-50s.  After a fun hard day it can be up in the low 70s.  Last Monday after a long session at the oval it was up to 80 for a while.  It's not surprising, it's obviously not uncomfortable in any way, but it certainly is noticeable while lying in bed.  All revved up with no place to go.  How much do you notice your post-exercise heart rate?

It's time for the traditional retroactive new year resolutions, things that I'm sure to accomplish last year:
  1. No high-speed crashes except the kind that take place on the skating oval and involve sliding along on the ice and then bonking into the pads without any real injury to anyone.
  2. No stabbing anyone!  Not even when they suggest running some poorly-thought-out sample on a mass spectrometer.
  3. Eat at some new and awesome restaurants.
  4. Finally visit some of the "new" museums in town that I've been meaning to go to since they opened a few years ago.
  5. Spend a lot of time on speed skates at the oval working on becoming a better speed skater, and get to know some of my fellow crazy people athletes there.
  6. Start doing crazy fun things like commuting to work by running.
  7. Clean out some of the junk I've accumulated.
Happy New Year!

I had been thinking of maybe taking it easy speed skating today.  Instead I had my highest-speed fall yet, followed by my fastest timed lap yet, followed by my fastest timed full 400 meter lap.  Then I think I finally figured out one of the big things I'm doing wrong with my right leg in the crossovers, and I think I'm improving that.  And then finally the coach sucked me into joining one of my fellow old guys masters skaters for the workout he was doing.  I ended up spending over two hours on the ice. 

Shortly after I started skating one of the Real Athletes had a fall on the front straight (no harm) and then shortly afterwards I had my own fall, which was the good kind, didn't hurt at all.  I fell entering the turn at full speed, slid along and hit the pads at pretty good speed, but I had enough time sliding to set up for it and it was pretty much a non-event.  After a few minutes rest I did a 37.1 in the inside lane, my fastest yet, followed a few minutes later by what worked out to be a full 400 meter lap, crossing from inside to outside lane, in 37.3 (I hadn't planned to do the full inside-outside lane lap, I was just avoiding traffic on the backstraight, but it worked out nicely).  Those both work out to around 37km/hr average.

I get lots of very good advice, but I often find it very hard to really understand what people are telling me about what I'm doing because I really have a hard time feeling what I'm doing.  I've been told I point my right foot out in the crossovers, but it doesn't really feel like it to me and I've had a hard time correcting since I don't really know what I'm doing.  I saw someone else skating and pointing his right toe out in the crossovers and realized that I was probably doing something similar, and the contrast with the motion of the right feet of those skaters we can confidently assume are doing it right was suddenly clear.  Now I have a better idea what to change, and I can already feel the whole motion of my foot in the crossovers is much smoother and easier now.  It's always really exciting to figure something like this out.

Oh, yeah, and then why not join in on a bunch of sets of 300-200-100 meters?  It was a chance to practice crossovers, entering the turns at speed in the draft of my fellow old guy masters skater (I need to remember to use the term "masters speed skaters" because it sounds so gosh darn great, like we're a bunch of experienced experts, rather than just referring to us as "old guys," which doesn't sound nearly as impressive).

In an ancient ritual that I made up myself six or seven years ago (plenty of time for it to seem like an ancient ritual) I did some ice skating to celebrate the winter solstice (as opposed to other random winter days when, most likely, I do some ice skating).  On Wednesday night at the Pettit Center our coach worked over the Wednesday workout group fairly hard, which was a combination of tiring and fun.  I'm getting less bad at skating in a group and maintaining a semi-stable gap behind the person in front of me, though, really, none of our group is all that good at it.  It's harder than it looks!  Thursday I was back at the oval on the speed skates after work for a while.  I timed some laps, did a 38.5 alone and not drafting anyone (just over 37 km/hr).  After that I went downtown to Red Arrow Park, across the street from City Hall and site of an outdoor refrigerated skating rink (and a Starbucks).  I thought it would be fun to mess around on the hockey skates.  Since vacation time is starting it was a lot busier than a typical Thursday night.  I've gotten used to being on clap skates on a 400 meter oval, and being on a tiny crowded rink is different.  Speed skaters are an attentive, organized sort of group, always aware that someone on the national team might be coming around at 50km/hr and you need to be out of the way or else on a predictable path.  I'm not used to the Brownian Motion chaos!  I am, finally, more or less used to the hockey skates.  The first time I put them on this year I pretty much fell over backwards immediately, not used to the tiny short blades with tons of rocker and the high, stiff boots.  You can lean way back on the long speed skate blades.

I'm also used to the ice on the Olympic training center's oval, finished to high standards by the skilled Zamboni drivers at the Pettit National Ice Center.  The ice has been really excellent lately and at the national meet this month an amazing number of competitors set new personal bests for the Pettit Center and a new track record for the 10,000m was set by Jonathan Kuck in an amazing effort.   Over at Red Arrow, not so much.  The ice was extremely rough when I showed up and then they cleared us off to resurface the ice.  I always thought of a Zamboni ice machine as an extremely low speed vehicle, but it turns out that they can be pushed to sufficient speed that even with the studded tires they will skid on the ice.  The driver actually had the thing in full drifts in every turn he made, aggressively cranking the steering into the skid as the machine slid sideways.  I had no idea that was even possible!  On the one hand, you have to admit the job went very very quickly.  On the other hand, I've never seen such a poor resurfacing job from a Zamboni that didn't have major mechanical problems.  It was hilarious!  I'd never even imagined such a thing!  So, overall, it was a wonderful amusing time at Red Arrow.  (But today I just went to the Pettit.  Where the ice was very nearly perfect.)  After the holiday vacation time is past I'll have to go back to Red Arrow, preferably on a nice cold night that discourages most of the normal people from showing up, because fast laps on the tiny space are fun when the rink is empty, as is being outdoors at night with the city all around lit up, and maybe a nice cold wind blowing. 

Today was, as you might imagine, a relatively uncrowded day at the oval during the speed skating session.  I always joke that you can't take the coaching out of the coach.  Bob shouted some advice to me as I practiced starts, though he's not normally coaching me.  He just can't resist being helpful, and since most of the elite competitors he's normally coaching weren't around I guess he figured he might as well give me advice.

Sure, sometimes science is dull.  Scientific papers tend to be specifically written to be dull.  But sometimes someone gets the chance to write a more unusual paper. 

The Thermo LTQ Velos Orbitrap mass spectrometer is an amazing piece of hardware.  If you've been in the instrumental analysis business you may have used equipment that gave amazing results on the rare occasions that it worked at all.  The Orbitrap not only produces great data, it actually works most of the time.  In our lab we just can't get over how well this thing actually works in practice.  You can go from vented to sub-10-7-torr in literally a few minutes and down to operating pressure in the 10-10 torr range with a single overnight bake-out. A month after calibration it can still be within four or five ppm.  It easily delivers resolution better than the promised 100,000 FWHM at 400 m/z.

If you really want maximum mass accuracy, better than 1 ppm, you really need a lock mass, an internal mass standard.  I'm just amazed at how stable the external calibration is over days and weeks-it's vastly better than our Q-TOF-but nothing beats an internal standard for maximum accuracy.  The question always is, though, what to use and how to introduce it into the system.

It turns out that there are some background contaminants right in the air that you can use if you can figure out exactly what they are and can get a reliable signal.  Polydimethylcyclosiloxanes work great.  They are in all sorts of ordinary household products, and thus in the air, and so you'll always see at least a little signal.  If you need a stronger signal, all you need to do is set a supply of the calibration compound near the mass spectrometer source and you'll get a higher concentration.  For example, see this article, "24 Hour Lock Mass Protection". "We devised a strategy to improve its performance by increasing the external abundance of calibrant molecules in laboratory air."  "This method involves a simple laboratory setup using common laboratory hardware and truly off-the-shelf reagents."  Yes, they set a tube of "Lady Speed Stick" deoderant by the mass spectrometer source, as a supply of calibration compound.  Really.  I have not personally tried this yet, but somehow I think I will.

I think I'm learning the way this works. Any workout plan the coach has that includes the word "interval" is going to hurt. "Tempo" means the workout will hurt. Tempo intervals, yes, for sure. If the coach explains the plan and asks, "does that sound easy or hard?" that probably means it's going to be hard. But we do this because it's fun! Or something like that! We're convinced it's fun! It's fun sprinting down a straight, coming to the end, standing up and coasting and leaning way over in the turn way out in the outside lane because it turns out you are going pretty fast. Keep up the training and you can go faster, and going fast is highly prized among speed skaters, as you might imagine given that our sport literally has "speed" right in the name.

After last Wednesday's skating workout (the one where I had the crash I described here on my Google+) our skating coach had a great little motivational talk with me. He said that there are a lot of things I need to work on with my speed skating technique, which I'm well aware of, as is everyone who has seen me skate. But he also noted that I'm demonstrating that I can keep up with skaters who have much better technique, which implies that if I improve my form I ought to gain a lot of speed. I hadn't really thought of it exactly like that.

He's had me working specifically on getting my right foot past the left in the crossovers lower and better. The fact is even when I do hit the left skate with the back of the right blade I don't actually crash (usually) so it shouldn't be too frightening to work on. One of the other guys has taken some iphone video of me skating so I can see what overall position I'm in. I, at least, find it surprisingly hard to feel from the inside what position I'm really in, compared to how it looks from the outside. The video is both very helpful and moderately hilarious, with the phone trying to figure out which way is up using its accelerometers while he holds it at a funny angle and goes around a turn at high speed. The phone probably gets motion sickness and the video always seems to get displayed upside down when we play it back, but even so I can see what I need to change.

The other thing I keep thinking is how much fun it is to skate with my crazy friends at the oval. All summer I was the crazy exercise guy at work, not just bicycling the 14km to work most days but sometimes doing the commute by running. I work at a medical school, so pretty much everyone thinks that exercise is great and everything, but I was sort of on the extreme end of it. It's great to find motivation within yourself. But we are basically a variety of social monkey, so getting some extra motivation from your fellow monkeys is also helpful. Now I find I'm hanging out with people with lives and jobs who are at least as excited about speed skating as I am and who are really working at it, plus we are out on the oval with all-out elite athletes who demonstrate to us what humans really are capable of. By comparison, we normal people are not really working at it so hard. Now instead of feeling like I'm the crazy exercise guy I'm thinking maybe I ought to be doing more weightlifting. We are all crazy and, frankly, we'll be the first to admit it.

I've joined the Wednesday evening workout group many of my speed skating friends are part of. I think clearly the best part of the interval workout (to the extent there is a best part of an interval workout) is the part where the coach lays out the plan. The plan is something along the general lines of "You'll skate 300 meters, rest 300, skate 300, rest 200, then 200 and 200, and twice 100 and 100, and..." and so on. And I'm thinking, dude, wait, I'm still just standing here and you haven't even finished explaining the workout and I've already forgotten most of what you said. We're going to get started and our brains will stop working due to lack of oxygen and we'll be reduced to doing what we always seem to do during the interval workouts, which is shout "Wait! Wait! What are we doing next?" to each other. Somewhere in the world I'm guessing there is a coach who is a former auctioneer. "Five five four hundred three hundred three hundred two hundred three hundred two hundred do I hear five hundred?"

Those skaters are just screwed.

Fall

I know a lot of people really love the in-between seasons, spring and fall. I've never much liked them. Summer has long long long days and warmth and lots of fun summertime activities. Winter is cold and dark and features snow and ice upon which you can ski or skate, and there is a notable lack of mosquitoes. Spring is dead and brown and wet and muddy and cold and wet. Fall is wet and cold and dark and covered with slippery dangerous dead leaves. We're very near the point where there is no time at all to go and stop anywhere on the way home from work without ending up traveling in the dark, and I'm waking up in total darkness.

This year I've got new speed skates (Bont Jet boots and Maple Blizzard blades), and the (indoor) long-track season has already started at the Pettit National Ice Center here in Milwaukee. I'm seeing my speed skating friends out on the ice again, and I'm getting back in the swing of our crazy sport. Early fall is looking like a lot more fun this year. I have lots of fun in the summer but aside from the organized multi-thousand-runner race I was in, mostly it's fairly solitary activity. You wave to people. Very rarely have some sort of chat. The Pettit center, whether running or skating, is a much more social experience, and I like it a lot. I'd sort of forgotten how much I like it. It's now my third year speed skating, and I'm getting to know a lot of the skaters. It's also fun to now go from being the crazy exercise guy (running 14km to work!) to being the slow guy who obviously hasn't been working out very hard. My tribe of crazy people, they is here! And they are crazy. One young woman I could just manage to keep up with last year has been working very hard over the summer and now maybe I can stay with her for a lap if she doesn't go too fast, but not longer than that! On the other hand, I've been cycling and running all summer and I really do feel strong, and now that I have my own skates (with my own blades that I obsessively sharpen) I can focus on improving and not on getting adapted to different skates. Even just today I feel like I'm really getting a better position and, though it sounds minor, better arm swing motion, which is really making a difference. (Seriously! Swinging your arms right is important on ice! As far as I can tell, everything is important.)

In the book Speed On Skates by Barry Publow, as the last item in a list titled "Interesting Research-Supported Facts about Speedskating Biomechanics," we find this:



  • Speedskaters are regarded to be generally better-looking than other athletes, to train harder, to have a higher tolerance for pain, and to be more friendly than most sport athletes, in the author's unbiased opinion.



I'm sure that's unbiased. I will say, based on my experience looking at athletes, speedskaters sure are, on average, a really good-looking group of people. It's also a generally friendly group of people. I see speedskaters who train very hard, though I don't really see the elite athletes in other sports whereas I do see really elite skaters at the Pettit Center, so of course they train like monsters compared to normal people.

Running

About two years ago I jokingly asked just how much running someone can do without having to admit to being one of those runners. I think it's safe to say that whatever the limit is, I'm past it now that I've taken to occasionally running to work. 14.14km each way (8.8 miles for any Americans in the audience.) It's only 7km more than a half marathon but with a long break in the middle, so no problem, right? For some reason the trip home always feels longer, though each time I do this it's faster and feels easier than the last. It does make one appreciate the invention of the wheel. By bicycle this is an easy, routine trip, easily made every day, generally in something between 34 and 40 minutes. Running it's been between 1:16 and 1:25, so I do have to get up early. It's fun, though. Cyclists (which is always what I've primarily thought of myself as) get to cycle to work or to other actual destinations. Runners mostly just exercise in irregularly-shaped loops (or sometimes regularly-shaped loops). Actually going somewhere is a special treat. The last trip to work I ended up running along with someone for about 1.25km, having a nice chat with her. Driving a car you never get to chat with your fellow motorists, mostly you are limited to the "you're number one!" hand gesture (as they call it in auto racing), or shouting something like [bad word] you! You [bad word]! That's just not the same social experience. It's possible to have a conversation while cycling, too, and I've done that a few times as well.

The other people at work do think I'm kind of special, not that they didn't before anyway. I work at a medical school, however, so this sort of thing may be weird but it's the good kind of conspicuously physically fit weird.

Good eyes

My eyeglasses are getting old and just worn out, and before buying new ones obviously I figured I ought to get my eyes examined. It's been about 10 years, longer than I had thought. I saw the eye doctor this morning, it turns out I can see somewhat better than the average and there has been no measurable change in the lens prescription that I need. No glaucoma, no sign of cataracts, my retinas look just fine. My father had macular degeneration late in his life. The doctor said that besides genetics, which you can't do anything about, the biggest risk factor is smoking. I noted that I ran to work yesterday, 9 miles (14km) each way... She said that obviously the diet-and-exercise thing is pretty well taken care of in my case! (Endurance athlete visits the doctor, says that he isn't planning to take up smoking...) The only thing I've noticed about my vision is that the extreme close focus, not the reading or the fine work inserting the nano-emitter into the tiny sleeve into the tiny fitting sort of thing but the nose-almost-touching sort of thing that isn't really a practical important ability, isn't what it used to be, but, hey, I'm 39. So, all good on that front. I'll have to go eyeglass shopping.

I suppose I really ought to schedule a general physical exam, too. I mean, if the mass spectrometers get Preventative Maintenance visits from the service engineer, I ought to as well, right?

I ran in the Summerfest Rock 'n Sole half marathon on Sunday July 10. This was, yes, the race that ran out of water at some of the aid stations at some points in the run on a beautiful hot humid July day, with some number of runners ending up hospitalized. That said, with over five thousand runners, some people had better or worse experiences than others, and my run went just fine. I finished in 2:08:11, 964th place out of 2995, 599th of 1356 men, 79th of 183 men age 35-39. Considering the warm weather, some amount of delay getting water at each station, and the fact that I deliberately wasted a bit of time taking photographs while running the race, that's a reasonable time for me. My real goal for the event wasn't the time but the chance to run on the bridge. I figured I'd do the longer run instead of the 10k since I've run the full 21.1km a number of times by myself and occasionally do my 14km-each-way commute to work running, so I was prepared to run the full distance.
