Tour de Greenbelt Routes & GPS App

Route Marking Info

The 50- and 25-mile road routes will be lightly marked with arrows at turns, but you will navigate the course using the free Ride with GPS event turn-by-turn navigation. It works just like the GPS in your car— showing your location on the map on your phone screen and announcing upcoming turns with audio and on-screen cues. You will need a fully charged phone and a place to mount it on your bike.

The Gravel Grinder routes will not be marked, but will have free Ride with GPS event turn-by-turn navigation for your phone. There is one route with more advanced riding of about 40 miles and another shorter route at around 29 miles.

Many thanks to our volunteer route-builders: Dan Tieger, Noah Leavitt, Charlie Mann and Brad Westbrook!
