Denver Colfax Marathon expansion

Entities: Andrea Dowdy · Denver Colfax Marathon · United Airlines · Denver International Airport

Overview

In July 2026, the Denver Colfax Marathon highlighted its charitable impact, reporting that the relay prize pool had exceeded $1.3 million since the event’s inception and that more than $10 million had been contributed to local charities. The race weekend drew close to 28,000 participants, marking the largest running event in Denver’s history.

Later that month, organizers announced a new “5K on the Runway” race at Denver International Airport in partnership with United Airlines. The limited‑capacity race sold out within six hours—significantly faster than the 2022 edition—and will feature a post‑race gathering in the airport’s main hangar. Together, these developments show the marathon’s ongoing growth, the addition of novel race formats, and expanding community and corporate collaborations.
