The bottom line
A small race that trades atmosphere for room to run.
Colorado Springs Marathon, Half, 5K, and Kids K is a strong choice for a first marathon, and the course rolls gently without any sustained climbing. The tradeoff is atmosphere: expect long quiet stretches and few spectators.
A loop course around Colorado Springs, CO, with steady rollers that reward even pacing.
