Nature Coast 100k2026

The Nature Coast 100K is a unique ultramarathon held on Florida’s scenic Nature Coast State Trail, starting and finishing at the College of Central Florida’s Jack Wilkinson Levy Campus in Chiefland. Runners and ruckers will tackle a fast, mostly flat paved rail-trail course through rural North Florida, completing three out-and-back legs connecting Fanning Springs with Cross City, Trenton, and Chiefland. With 100K and 50K distances, generous 24-hour cutoffs, well-supported aid stations, and plenty of classic Florida scenery along the way, the Nature Coast 100K offers an approachable course for first-time ultrarunners while still providing a rewarding challenge for experienced athletes.
