Awesome, you have to check this out!
I am founder and organizer of Peak to Peak Cycling in Boulder, Colorado and was lucky enough to stumble upon StravaLeagues. David the developer is super helpful as he works on iterations of this site and we are in the middle of a 17 week League that mets every sunday. Check it out in action here under our Strava Leagues menu. www.p2pcolorado.comReview by: Jeff P2PCycling
