May through August is peak riding season for me. I say this because all the larger events I like to participate in are mostly in September and October. My problem is my job is hectic and very time consuming as well as physically draining during this time. I manage to ride on Saturdays and Sundays, but I always feel as if this is not enough. If I were to squeeze in two 10 mile rides in late in the evenings during the week is this along with my more intense riding and longer distances on the weekends enough to help me stay in century shape? Does anyone else here have the same situation I do? If so how do you adapt so you dont regress?
