When it comes to running in Bend, the team at FootZone is the most trusted source for great route advice. In fact, they’ve mapped out a series of road runs between 3 and 10 miles in length to help you choose the best streets to sprint on. All of them begin from the FootZone store near the downtown business district on NW Riverside Boulevard and zig zag back and forth across the river for various lengths. The longest routes utilize Mount Washington Drive, the wide looping road that encircles the western border of the city.
Their route map page also has suggestions for trail runs.
