I'm a new cyclist and using Friel's Training Bible to design my workout schedule. I'm 25 and in fairly decent shape (not cycling shape though I've come to learn). My goal is to do a few crits next season. My question is regarding workout duration. My work/life schedule allows me about an hour in the mornings and I also have the option of about 45min-1hr to workout at lunch. I try to get a 3 hour ride in on the weekend and 1 day of rest. Will workout durations of 1 hour or less hamper my training abilities? I'm considering 2-a-days for my heavier weeks because right now in "Base 2", I'm having a hard time scheduling 10 hours of workouts in 45 minute increments.
Also regarding intensity, I don't think I'm getting much out of a 45 minute ride in Zone 2, will moving into higher intensities hurt my training later?
