About
November sees RMRR running at Prairie Gateway Park in Commerce City. Our 15Km Trophy Series and 5Km races will start at 9 am on Sunday, Nov 3rd. The 5 km race will start at approximately 20 to 30 minutes after the beginning of the race. This is our next to last race for the year, and a great opportunity for people to improve their Trophy Series scores. We run on a relatively flat and fast packed gravel trail – good surface for comfortable running and some faster times!
