Antelope Island Buffalo Run - Spring Classic
The Antelope Island Buffalo Run is an annual spring trail-running event held on Antelope Island with views of the Great Salt Lake. The course runs on rolling singletrack through desert grasslands and passes areas where wild bison roam, and it brings together a regional trail-running community.
The event began in 2006 with about 150 runners in two distances and has since expanded into a multi-distance festival featuring three race distances. Race fees vary by distance and registration date; example ranges published are: 50 Mile $180 to $240, 50K $130 to $175, 25K $90 to $130. Race fees do not include the event processing fee or taxes.
Distances and approximate climb:
- 50 Miles - ~3,428 ft of gain
- 50K (31 miles) - ~3,038 ft of gain
- 25K (16.48 miles) - ~1,687 ft of gain
A sponsor provides a course-record prize purse for each distance: $500 for the 50 Mile division, $500 for the 50K division, and $250 for the 25K division, awarded separately in the male and female divisions. The event materials reference detailed course pages for each distance and a runners guide published for the event. Visit the organization's website for the most recent information.
