I'm curious as to how many hours per week you're training or how many miles, and what your FTP and other power numbers are if you have a power meter.
I'm just another 40 year old guy trying to stay fit, and I've been doing triathlons for the last couple of years. The cycling's my favorite and I'm best at it, so this year I'm trying to do some cycling races as well. I've been averaging about 20-25 hours per month on the bike, around 400-500 miles per month.
I hope to increase my power numbers this year, as my FTP's somewhere around 250-260 currently and I'm a not-so-light 180 lbs. I'm muscular and my peak and 5s numbers are pretty decent (somewhere north of 1100), so I hope I have the potential to increase the FTP numbers with more training.
Anyway, I've done a couple of criteriums so far this year, came in sixth in one and ended up OTB and got pulled in the other, due more to dumb racing tactics than anything else. I figure the tactics will come with experience.
I figure everybody loves to tell somebody else what to do..here's your chance to give me advice. No, I probably won't take all of it.
