Due to hevay peer pressure, I was coerced into signing up for a early spring century ride...its in a month and a half. I have done century rides before, but my work shedule this winter left me with little time to keep in shape. The long and short of it is, in Oct., I did a 12 hr mtb race. Now, I am 10 lbs heavier, and get winded after an intense 45 min on the trainer (which i have been doing maybe twice a week).
I live in the midwest and it is snowing out now, so putting in the miles outside is not really an option. Are there any "crash course" training guides to get be back into shape in 6 weeks?
