About this Event

The World's Slowest Marathon 26.2 miles. 24 hours. For Denver's unhoused neighbors.

We're running 4 miles every 4 hours — starting July 17th at 8 PM and crossing the finish line at 4 PM on July 18th. Through the night, into the sunrise, and all the way to the afternoon. Every mile and every dollar raised goes toward Neighbors, a Denver nonprofit doing frontline outreach for our unhoused community.

Our goal: raise $6,000+ for Neighbors to help them supply food, supplies, and stories to our unhoused neighbors in Denver.
