Mainly to Sciguy and Jackmott. If you guys recall, last winter, I said that I tend to see my highest FTP in the winter when I am XC skiing and biking a lot less. My theory is that I cannot train as hard as often on the tri sports, and my aerobic engine gets more efficient, even though my bike volume is very low in the winter.
To experiment on this, after my last tri in October, I basically wound down the biking. In November, I did just under 500K and in December just under 400K of riding, most of this was moderate intensity short spinning on my rollers (30-40 min at a time). I ran a fair amount both months, especially a lot of treadmill hill intervals at 8-12% grade. Over the last year, I found that whenever I was on biz travel I would literally get back home after running a lot of treadmill hill repeats and see my bike wattages go up, but that was typically after missing biking for 5-14 days at a time not on low bike volume for 2 months.
In Decemenber, I added a decent amount of XC skiing, mainly classic style and also did 5 hard speed skating sessions, with intervals and also a 5000m TT at the oval. In the past, I had noticed that whenever I do more speed skating my trainer sessions are that much better, probably because by definition every speed skate session is intervals (kind of like swimming, you just don’t go to the oval and putter around in circles for an hour).
Anyway, yesterday, this was an unplanned workout, after training just under 5 hours on Saturday (speed skate, classic ski, skate ski, run spread through the day). I first got on my spin bike and rode 20 min easy, then got on my treadmill and ran 25 min to warmup with a bunch of 30-60 second hill intervals to get my heart rate up and legs working, got on the CT, warmed the tire up, put in a 30 min TT course that I do every so often, and logged a higher wattage than I had through the entire tri season. The week before Vegas when I had my best bike ride of the year, I averaged 248W, yesterday I did 254W and was only going at 95-97% perceived effort, only because I have been biking so little that I was unsure what I could sustain. At the halfway, I was at 250W. With 7 minutes to go, it felt OK, so I biked the last part at over 270W for most of it. I was actually quite surprised ending up where it did. It was hard, but not crazy hard. Ran 10 more minutes on the treadmill and had good legs to actually pick it up. The TT befere Vegas was during a taper week on fairly fresh legs. Yesterday it was on totally trashed legs.
3 other factors in December:
overall training volume up over Novsleep volume up over the last 2 weeks of holidayszero work related stress last 2 weeks
I’ll weigh in later today to see what my weight is at when I get to the gym.
