About this race

The Great River Road Road Race (GRRRR) is again at Pikes Peak State Park this year. This year, both the 5 and 10K races are USATF-certified and sanctioned. The 5K is certification # IA 24009MF, and the 10K is certification # IA 24008-M. The chip-timed race will follow the traditional route starting in the park. From the parking lot, runners will follow Pikes Peak Road west to the Great River Road, turn south, and follow the Great River Road out to either the 5 or 10K  mark and return on the same route. It will be a fun and fast run with slightly rolling hills. After the race, there will be an awards presentation and a complimentary untraditional pancake breakfast. We hope you can join us!
