From the Organizer
Rocky Mountain Road Runners holds a monthly Trophy Series in the Denver area. We provide a low-key, low-cost racing environment. Everyone is welcome to run with us!
The 8mi race uses a handicap start system, slow-to-fast, spread over ~45 minutes. This gives everyone a chance to win. We'll use your estimated finish time to assign you a start time with others the same speed.
All 5k racers will start ~15min after the first 8mi starters.
Our October race is at Star K Ranch, in Aurora, along the mostly dirt Sand Creek path.
