Run.GPS is a Google Maps mashup which allows users from all over the world to upload their training routes. Routes are mapped out, timed and measured; members can post their average speed, date, and duration. To upload your training circuit you'll need a GPS enabled device, of course, a PDA or Smartphone with Windows Mobile, and a Run.CPS Trainer license (there is a free trial version). The most endeavoring athletes get a spot on the homepage. Every member gets profile space and there's messaging available. Registered members can also take advantage of the Route Planner tool to plan and map new routes.
