I'm a cat 4 who hasn't trained or raced for over a year. I suddenly got the urge to do a local crit in 4 weeks because it is literally 2 miles from my house. Hard to pass up. Only thing, I have not done any bicycle-specific training for a year. However, I am in decent cardio shape due to daily commuting 16 miles and also martial arts training which includes some high intensity sparring. I know I would get dropped in a crit if I raced today. Question: is it realistic to expect that I could train hard enough in 4 weeks time to get in shape for this crit? Or should I not even bother and just do a slow buildup for next season.
Another factor: the course is completely flat, no climbs at all.
