Antelope Island Buffalo Run

Antelope Island Buffalo Run is a trail event in Syracuse, Utah, held on Antelope Island on March 13, 2027, and organized by Buffalo Run Adventures. The schedule is staggered by distance: the 100-mile starts at 6:00 a.m., the 50-mile at 7:00 a.m., the 50K (31 miles) at 8:00 a.m., and the 25K (15.5 miles) at 9:00 a.m.

Whether you want a first trail race or an early-season 100-mile, the lineup has a spot for you. The 25K is approachable with eight to ten weeks of training, the 50K works as a first ultra after a 12- to 16-week build, and the 50-mile is a logical step for runners with a few 50K finishes. The 100-mile in mid-March means a winter training block, so plan on 20 to 24 weeks with back-to-back long runs and at least one overnight session. Island trails on the Great Salt Lake can be exposed, so pack layers for wind and sun and carry your own fluids between aid stations.
