Route Info

Swim: The Boulder Reservoir will have water temps in the 70’s. The traditionally smooth lake will launch you on your day. The one-loop course will travel north first along the reservoir dam and will head west and then south. The first of two transitions will also be at the Boulder Reservoir. Click here for map.

Bike: This 75 mile route takes you through flat roads, hills, and fantastic scenery. A favorite for athletes and novices alike. This route will be closed to other cyclists and road traffic during the event. Click here for map.

Run: This is a two-loop course with 3 out and backs on each loop. We call it the “Flux Capacitor”. This course features everything about Boulder we love. A well-shaded bike path and plenty of spectator viewing points for your family and friends. There will be aid stations approximately at every mile. Click here for map.
