The 600k is composed of two loops in the shape of a figure 8. Like the 300k, it starts in Flagstaff and goes to the Grand Canyon which is the most northern point. The second loop starts in Flagstaff and travels south through Oak Creek Canyon and Sedona. It crosses the Verde Valley and then climbs Hwy 260 (General Crook Trail). The route travels past Mormon Lake on Lake Mary Road before returning to Flagstaff.

Terrain: The 300k and the first loop of the 600k are strongly rolling. The second loop of the 600kstarts with a plunging descent down Oak Creek Canyon and then a steady 25-mile climb up Hwy 260 to the Mogollon Rim.

Directions to the start

Lights: Required. There will be a light inspection at check-in to verify front and rear lights are working and are sufficient for night riding. Also required are reflective vest or sash and ankle reflectors.


Accomodations - The start/finish hotel in Flagstaff is the Motel 6 on Woodland Village Blvd. It can also serve as a sleep stop after the first loop of the 600k which is at mile 211.

Accomodations are the rider's responsibility. This will allow us to keep costs low and provide riders more flexibility. In this way, riders riding through the night on Saturday won't have the expense of a hotel. If any 600k riders want to share a room on Saturday night for a couple hours, I will facilitate that.

RV: There are several hotels close to the start in Flagstaff. Across the street from the start is a Walmart and Bashas (grocery store) where overnight parking is permitted
