I have been doing training group rides for several years with racers. I have trained with various level racers on there group rides, Cat 4- Cat2. Is it possible to truly compete with only 7 hours per week training ? Once the season is in full gear some of this guys are good for 250-400 per week. I know I can hang for 85 percent of the time, but time seams to be the limiter.... I know training gains acheived is personal..intervals..strenght.. Any thoughts?
