XTERRA Real Race Report
So after nearly eight months of no racing, Maffetone training that never had my heart rate over 140 bpm, influenza, pneumonia, and a slow march through base training, I finally got to uncork one!
And I went… slowly.
It was disappointing to go slower than two years ago, which was close to this year in course conditions. The swim was slow, thanks to freezing conditions that forced more breast stroke than I like. The bike was a little slower as well due to mud and some mechanical problems with my brakes. I knew my brakes were mushy going in, but I thought they would hold for two laps. They held for a lap and then the rear brake began to fade dramatically. Not as bad as last year though, when they failed completely, destroyed a rim, and left me walking the downhills. I shouldn’t be disappointed considereing my lack of training or racing at high intensity. After all, this was the first race of the season. But I am disappointed considering the improvement in my MAF tests compared to last year. I thought I would be going a lot better.
What was puzzling was that I felt great while racing. Even the swim, which I haven’t trained much at all, felt comfortable after I got used to the ice cold water. The bike was a challenge because it’s been months since I rode the mountain bike on anything remotely technical. While challenging, it was fun to ride those Granite Beach trails. The bike course is real mountain biking: lots of single track, and you’re always actively doing something, climbing, descending, negotiating rocks, turning through tight and twisty singletrack. You have to concentrate. The run felt pretty good as well. My stride and cadence were what I wanted them, I didn’t have GI issues, but my time shows the truth: I didn’t go fast.
I wore my Garmin hrm so I could graph my heart rate for the bike and run sections and see what happened. I found that I averaged 170 bpm, and cruised a lot around 175 bpm. I noticed that around 180 bpm the door to the hurt locker slammed shut, and I had to back off, usually at the top of a climb. So, since I have done all of my exercise under 140 bpm, but race from 165-175 bpm, it appears that I need to do more anaerobic, race pace training to get used to going fast. Also, the fact that I “felt good” might be a red flag. After all, isn’t racing supposed to hurt? At least a little? I think I held back a little too much, perhaps due to being out of practice.
So going forward?
More mountain biking. Spring is here, the trails are drying out, my bike is tuned.
Readjust my MAF training range up from Maffetone’s formula of 140 to Mark Allen’s version, which is 145, especially on the run.
More volume. I felt that I faded in the second half of each event. Probably due to lack of truly long rides and runs.
What about anaerobic effort?
I will hold off anerobic training for another month and just use racing for that training effect. I need to continue to build my aerobic base because it still lags behind. I may readjust my range upward again to follow what some coaches recommend by basing my MAF off of lactate threshold instead of the 180 formula. For the moment, I will keep it low since I am still getting benefits.
After all, if it ain’t broke, don’t fix it!
