STFU & Run at Sleepy Hollow State Park!

Summer Trail Fest Ultra (STFU) – 50K, Half Marathon, & 5 Mile

Yes, we know what it stands for. STFU is the perfect summer trail race, whether you’re chasing your first finish or a new PR. The course at Sleepy Hollow State Park is 90% scenic, runnable trail with generous cutoff times (20:00/mile for the 50K and 45:00/mile for the Half). You’ll find well-stocked aid stations, clear course markings, and a supportive trail community. All three distances also feature Ruck Divisions!

After your race, head to the beach and refuel—Trivium will be on the grill serving burgers, hot dogs, and sides for all participants. New in 2026: Spectators can join the celebration with a picnic ticket! And if you’ve run Winter Trail Fest, don’t forget—your STFU and WTF medals magnetically connect. Need a little push? Quit the excuses and STFU & Run!

STFU & WTF Connecting Medals

Each year, we create a new design where finisher medals from Winter Trail Fest (WTF) Half Marathon and 5 Mile and STFU combine to make one giant medal!  2026 medals coming soon.
