Finish the year one mile at a time with RUNboulder. Our free December mileage pilot runs December 1–31, 2026. Run anywhere and build toward 25, 50, 100, 150, or 200 miles. Choose a goal that fits your training; every pace is welcome.

How it works

Register, then submit the date and distance of each run through RunSignup. Eligible activities add together toward your monthly total.

Pilot rules

Running and run/walk workouts count: road, trail, track, and treadmill. Cycling and other activities do not count. Log each activity once, using its distance rather than your cumulative total. Only activities completed December 1–31, 2026 count. Submit final activities by January 2, 2027 at 11:59 PM Mountain Time. All deadlines use Mountain Time.

Mileage is self-reported. Keep activity records so errors can be checked. Automatic watch or Strava syncing is not included. Entry is free; no physical merchandise or prizes are included.

Run your own routes, follow local access rules, and adjust your goal as needed. Community information: RUNboulder.
