Out of curiosity how many of you get mountain bike rides in after work? How does your mountain bike and commuting ratio stand during an average week? Reason I ask Is because I often times bring my mountain bike on my car to work and hit the trail after work. On day that I'll commute I'll have to trade commuting for mountain bike riding that evening. Which makes sense because I'm not mountain bike riding every day of the work week anyway. Do you find that after a long evening mountain bike ride your commute is harder the next day or vice versa?
