Event Description

RMRR provides consistent and individualized marathon training opportunities for runners of all abilities.

RMRR’s Marathon Training Series provides 10 Mile and 20 Mile 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 Marathon Training Series races:  RMRR members, guests, training team members, everyone!  The course is clearly marked, and mile markers will help you gauge your time.  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.  We make it easy for you to work on your pace, your nutrition and drinking, and getting everything ready for your big race.

Please note that for everyone's safety dogs or running strollers are not permitted on our courses.  Thanks for understanding.
