October in Denver is made for moving — crisp mornings, golden cottonwoods, and that thin mile-high air that makes every run feel earned. The October Challenge is Eventism's city-wide call to move every single day: 5K around Sloan's Lake, your neighborhood park, or anywhere you like. Run with the community, log your miles, get your face on the Challenger Wall — and every mile supports Black health equity in Colorado, with a $50,000 fundraising goal for the month.
