I play hockey 2-3 times a week. I don't commute on game or practice days because of the amount of gear involved and I usually go straight from work to the rink. However, I do try and get in 5-10 miles of rec riding on the weekend game days. I can usually get a better and deeper stretch if I've put my legs through some work.
Next summer I might start playing in a league that is about 5 miles away and I thought it would be cool to throw the gear in the kiddie trailer.
