About

A Colorado out-and-back charity ultramarathon on an out-and-back course up Mount Werner to Rabbit Ears and back, with seven numbered sections, significant elevation gain, and a festive post-race party.

Catering & aid stations

Aid stations on course provide food and drink; specifics are detailed in the Runner’s Manual and on course maps (not Pacemaker lines).

Pacers

Pacemaker/Pacer runs are offered: on race day, Pacers join their target start waves shown on the Start Schedule (Renntag für Laufende) and wear Pacer flaggen. Refer to the Renntag schedule for target times per wave; pacers are optional and identified at the start corral.

FAQ

What is the refund, transfer, or cancellation policy?

No refunds, deferrals, or transfers are offered for the 100 mile or 50 mile runs. A partial credit for next year may be available if you withdraw before the specified deadline and your slot is taken from the waitlist; otherwise, the amount supports the charities.

Are there early bird start options?

Yes: 50-mile participants may choose an Early Bird start at 5:00 AM if desired; 100-mile participants may choose an Early Bird start at 7:00 AM. Note that course support (e.g., Mt. Werner aid station) may not be ready for Early Bird starts.

What is the time limit?

50-mile has a 15-hour limit (finish by 9:00 PM); 100-mile Tortoises have 36 hours (finish by Saturday 9:00 PM); Hares have 30 hours (finish by Saturday 7:00 PM). Early Bird starters must still finish by the same finish times to receive an official finish.
