Run for Charity

We have one of the largest Charity Partner programs in the country! More than 210 local Colorado and national charities participated last year. Choose a charity to run for when you register and race for a good cause. The charity you select when you register will contact you.

5K course and map

We are excited to have our  5K course Start and Finish at the Marathon Start and Finish Line! The course wraps around City Park and Ferril Lake with terrific views of downtown and the mountains.   The adjusted course map (new for 2017) with this new Start Line can be viewed by clicking here.
