MAF Test Musings: Racing, Losing, and Regaining Fitness
Good news from the track: My fitness is once again headed in the right direction. Apparently, spending 4-8 hrs on your bike going as anaerobic as possible wears a body down. Who would have thought it? I saw my MAF test pace decline about 30 sec per mile through July, and the graph of my HRV remained relatively flat. I was overreaching, and for once, I was smart about it. As school started I took my midseason break.
And it worked!
I have seen my highest HRV scores ever, and the average is up 10 points for the last month. That has never happened before. And my MAF test pace is back to roughly what it was at the start of summer, before all the marathon mtb races. What does that mean?
1. My aerobic fitness had regressed due to the heavy anaerobic demands of racing. HRV and MAF pace measure that quantitatively, but I could also qualitatively feel the fatigue build, and for the first time recognize it early enough to do something about it.
2. My autonomic nervous system is in a good state of balance and is not overstressed.
3. My aerobic system is recovered, and can once again move forward.
Speaking of marathons…
It’s marathon season, and I’ve scheduled a half marathon in October to continue to build toward a December full marathon. Now I just concentrate on long runs, and let the bike fade a bit into the background. For now, all training runs stay at MAF pace. No need to stress my anaerobic system for a marathon, it won’t be needed as much as the biggest aerobic engine I can find between now and then. Besides I had plenty of anaerobic hell in Tahoe this summer.
In other news:
The PCRM Kickstart is going well, but with so many yummy recipes to try, and only one of me to actually eat them, I’m a little overwhelmed. Oh well, nothing like a little eating challenge to inspire and use up the great fall produce.
