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!
