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.

Dates - We are offering two brevets: on 6/24 and 7/15.

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 - For the 7/15 event, there will be a $25 fee to cover course monitoring and bag drop. The fee is collected online when you register. The 6/24 event does not currently have support, so there is no fee. 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 - For the 7/15 event, we plan bag drop support at Walden, and some on-course monitoring. Riders planning an overnight break at Walden or elsewhere will need to make their own lodging arrangements.


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