Register Today for the 2026 Cat’s Tail Marathon!

The Cat’s Tail Marathon takes you deep into the rugged heart of the Slide Mountain Wilderness Area, and it throws absolutely everything at you. Steep climbs, technical descents, and the kind of rocky, rooted singletrack that keeps you entirely in the zone from start to finish. But the challenge is exactly why we show up! The course is 26 miles, point-to-point of pure Catskills grit.

There is nothing quite like the Catskills in late September. Crisp autumn air, the first brilliant pops of fall color hitting the canopy, and that perfect, cool racing weather. Best of all, you’re surrounded by one of the most supportive, dirt-loving trail communities out there. Come for the rugged miles, stay for the incredible people at the finish line.

September 26th will be here before you know it. Register today and get to work! Here is a clip following Jay Lemos down from Wittenberg Mountain during the 2021 race.
