RMRR Makes Marathons Easier
RMRR’s Marathon Training Series provides 10M and 20M races that are low cost, friendly, fully supported, and officially timed. All you need to do is focus on your running! Our races fit perfectly in training schedules for Colfax, Boulder Marathon, Chicago, New York, and other full and half marathons.
Everyone is welcome to MTS races: RMRR members, guests, training team members, everyone! The course is clearly marked with individual mile markers, and we've got aid stations every 2.5 miles to keep your fluids and energy high. We’ll time your run and provide results a few days after the race, and winners of each distance will receive ribbons and running store gift certificates. Our MTS training races make it easy for you to work on your pace, your nutrition and drinking, and getting everything ready for your big race.
Race day pricing is $5 higher for all individual races, $10 higher for race series signup.
This year our spring races will start at Platte River Trailhead Park at 88th and Colorado.
