Stampede the Trail 5K and Half Marathon

Stampede the Trail 5K and Half Marathon takes place on June 26, 2027, in Duncan, Oklahoma. Two distances are offered: the half marathon (13.1 mi) and a 5K (3.1 mi). Start times and elevation gain are not listed in our records.

Southern Oklahoma in late June is hot from early morning and the wind rarely helps, so a half marathon here is an exercise in restraint: run the first five miles at a pace that feels too easy and you will still be running at mile eleven. Freeze a bottle overnight and carry it — at this time of year the fluid you take with you matters more than any pacing plan.
