Lone Tree Reckoning Heavy 15K and 5K
The Lone Tree Reckoning Trail Heavy 15K and 5K takes place on November 14, 2026, in Loveland, Colorado, at 2939 N County Rd 31D. The event includes on-site and virtual options and uses trail terrain on a looped course.
The courses feature a mix of runnable stretches, climbs, changing terrain, and technical sections. Runners can expect sections that require hiking or slowing to navigate. The Heavy 15K covers just over 11 miles and has a 4.5 hour time limit. A virtual Heavy 15K option follows the same 11 mile distance with its own registration window.
Registration details from the organizer:
- In-person registrations open August 23, 2026 and close October 1, 2026.
- Virtual Heavy 15K registration opens November 2, 2026 and closes November 14, 2026.
- Published registration fees are $75.00 for the Heavy 15K and virtual Heavy 15K, and $45.00 for the 5K.
The original course plan included additional ranch terrain to reach half marathon distance. That section is not being used this year, so the inaugural event uses the available loop at just over 15K while preserving the intended climbs, technical terrain, and variety.
