A bicycle commute for me would be a little over 17 mi one way. Most of this (12 mi) would be on a multipurpose trail. The rest would be city streets. Is this too far for a commute? From what I can find it appears most people that commute only have 4-5 mi trips. I guess I'd like to know if 17 mi is excessive for a commute. Huh, just realized 17 is also the mileage my truck gets from a gallon of gas (~$4).
