Well that was an absurd amount of fun, racing from 7 a.m. to 7 p.m. on the flowing trails at Philip S. Miller Park. Thanks to the adults for racing and supporting the Colorado High School Cycling League - and thanks to the high schoolers for showing us how it's done on the trails!


We strongly encourage you to carpool. One car per solo / two cars per team will be permitted entry into the parking areas closest to the start/finish. All other vehicles will be directed to park in adjacent lots or to Auburn St., which is about a half mile to the start/finish.

Parking opens at 5 a.m. on Saturday morning. You must know your team name and team size upon arrival, as this dictates where parking attendants will direct you.

Please see our detailed parking map.
