100km Cycling Course



Gravel, Pavement, and Trail. 5248 ft of total climbing. A legendary mixed-terrain course that’s always fun no matter what the weather
Starts out with rolling gravel roads, a NEW loop at REEB Ranch, then climbs to the Rowena trail that traverses from Lefthand Canyon to Sunshine Canyon. Plunge down into Boulder for high fives, then roll up your sleeves and climb some more. The final stretch takes you back through dirt and finally a straight shot into Lyons. Hot food, cold beer, and live music awaits you at Oskar Blues.IMPORTANT NOTES:

1. There is a ‘neutral start’ from Lyons until the first turn off on 63rd. All riders must stay behind State Trooper until this turn off.

2. There will be a 1pm cut-off to enter the Rowena trail off of Lefthand Canyon. If you arrive to this intersection after 1pm, you will be instructed to ride back down Lefthand and finish the course).

3. Course closes at 4pm – all riders must be back in Lyons
