Coronavirus update
Updated 7-3-2020.
On June 15, we announced that we will not be able to reschedule the Denver Colfax Marathon for the fall of 2020. COVID-19 has changed all of our lives and has put a stop to mass gatherings. With the newest Colorado Safer at Home guidelines we knew that a safe, fun, robust race weekend this year won’t be possible. We looked at many options along the way, but we needed to shift our focus to 2021. Therefore, we are moving our 15th Anniversary Denver Colfax Marathon Race Weekend and Celebration to May of 2021.
Registered individual runners and team captains were offered three free options and had to choose one by June 30, 2020. The options were as follows: defer to 2021, defer to 2022 or run virtually.
Details and FAQs can be found here.

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!
