It is a GPS based running tracker.  It tracks routes, mileages, times, shoes used, and even tracks different public segments for leaderboards.  It keeps track of PRs and all that.  Its really a pretty cool site. 

It also has a social feature, where you can see all of your friends' runs and comment/like them.  My hope is that it is going to be a good tool to help our athletes be accountable to one another and to their training.  If they do their workout (even if not at practice, due to vacations, etc.) then their teammates will know it.  

The accounts are free to set up and use.  There is a premium version, which you are welcome to get.  (I dont have the preminum version myself, so I could not tell you whether it is worth it or not.  I will tell you that Ive been using it for a few years now and have loved the free version)
