Saturday, May 23 | Boulder High School

The Mile High Mile is back for its 8th season—bringing a high-energy night of racing to Boulder for runners of all ages and abilities right at the heart of the Boulder Creek Festival and all the excitement of Memorial Day weekend in Downtown Boulder.

This year, we’re introducing a new format designed to make the event more accessible, more flexible, and more fun—whether you’re chasing a PR or just showing up to run a mile with your crew.
