Lone Tree Reckoning Half and 5K

Lone Tree Reckoning Half and 5K is a trail running event in Loveland, Colorado, on November 14, 2026. The format detailed in the listing is a trail half marathon (13.1 miles) starting at 7:30 AM; a 5K appears in the event name, but no separate details are provided for it here. Elevation gain is not published, so treat the course as a Colorado trail with hills until you learn otherwise.

A trail half is a step up from road racing: pace will be slower, and hiking short steep sections is normal. Plan a 12-week build with a weekly long run on trails, gradually reaching 10 to 12 miles, and include some hill repeats. If you are coming from a road half, expect your finish time to be noticeably longer and focus on effort rather than pace. Given the 7:30 AM start in mid-November, arrive early and keep a layer on until the gun.
