About the race
The Lone Tree Reckoning Trail Heavy 15K and 5K is a trail running event on November 14, 2026 in Loveland, Colorado at 2939 N County Rd 31D. The courses use ranch and trail terrain and include runnable stretches, climbs, changing surfaces, and technical sections that require hiking or careful footing in places.
The event offers two distances:
- Heavy 15K : just over 15K (about 11 miles), 5 hour time limit
- 5K : shorter trail distance with mixed terrain
The Heavy 15K loop replaces an initially planned half marathon route; the organizer adjusted the course because one section of the ranch could not be used this year. The Heavy 15K loop still contains the climbs and technical terrain planned for the inaugural Reckoning.
Registration opens August 23, 2026 and closes October 1, 2026. Entry fees listed are $75.00 for the Heavy 15K and $45.00 for the 5K. Participants should be prepared to run and to hike over steeper or more technical sections. Visit the organization's website for the most recent information.
