Rocky Mountain National Park
from Trail Ridge Road
This single-loop ACP 600k brevet has over 8,100m (26,800 ft.) of climbing, which means it can be used towards the 8000m requirement of the ACP's Randonneur 10000 Award. There is a Park Service entrance fee to transit Rocky Mountain National Park.

The Route - Golden - Peak-to-Peak - Trail Ridge - Walden - Poudre Canyon - Horsetooth - The route travels from Louisville to Golden then takes the Peak-to-Peak Highway (9,250 ft. max elevation) to Estes Park and over Trail Ridge Road in Rocky Mountain National Park. Max altitude for the brevet is on Trail Ridge, at 12,183 ft. The route then descends to Granby and over Willow Creek Pass (9,683 ft.) to Walden, a good choice for taking a sleep break. Final high elevation is over Cameron Pass (10,249 ft.) followed by a 57-miles descent to the Ft. Collins area. After a climb over Horsetooth Reservoir, it's a flat to rolling finish into Louisville.

Membership and Fees - We are planning on no event fees, but as with our other brevets, you need to be an RMCC member. (membership dues cover our operating costs) and a RUSA member.

Logistics and Support - We currently plan for this to be an unsupported ride with no logistical support, as with our other brevets. Riders may wish to make their own arrangements for drop bag or other supplies, should they plan a break at Walden or elsewhere on the course. In that way, it's similar to our single-loop Laramie - Cheyenne 600k offered in late May.


We plan to use the Quality Inn - 303-604-0181 - as our host motel. We use them for our 1200k's as well.
