Marathon Relay - Corporate, Government, Public School Teachers, Open
What’s better than running 26.2 miles through the Mile High City? Sharing the miles with friends! Get a team of five to run Denver’s only 26.2 mile Marathon Relay. Most teams run for fun. Others run for bragging rights and money for charity.
It’s the largest in the US – because of the fun! Companies and government entities enter multiple teams in their industry division – like Construction, Healthcare, or Public School Teachers. Friends enter the Open Division.

Urban 10 Miler - a local's favorite
It’s the marathon course in just 10 miles! Perfect if you love the idea of running downtown, through the stadium, eclectic college campus, and waterways – but do not want to tackle a full 26.2 miles. It’s a point to point race, that starts a bit later at RMCAD, and then finishes with the marathon, half, and relay in City Park. Your bib has an RTD ticket to get back to your car. A Denver favorite!
