Colorado Runner - Colorado's running news, events and results source

The Denver Colfax Marathon, presented by Cigna Healthcare, is amplifying the energy of its race in honor of its 20th year in the Mile High. The city’s only marathon weekend is transforming its marathon and half marathon courses with a new experience: WOW at Every Mile.

There was more thrilling cross action happening around the nation this past weekend down in Huntsville, Alabama, as the 2025 RunningLane XC Championships were being contested.

Colorado runners know the truth: nothing compares to stepping outside and hitting a trail within minutes. No traffic. No long drive. No juggling schedules just to squeeze in a run before sunset.
