About the Run With the Horses Marathon
This Green River community race begins from Expedition Island and shares its weekend with the city's River Festival. The marathon remains distinct from companion half, 10K and 5K events.
Course
The road route climbs above Green River into exposed high-desert country before returning toward town. Elevation, long sight lines and limited shade make controlled effort important early.
Race-day weather
Mid-August in southwest Wyoming often starts cool, then becomes sunny, dry and windy. High-desert exposure can accelerate dehydration even when the air does not feel humid.
