Lace up for the Oak Tree Half Marathon and 5K on September 6, 2026, in scenic Geneseo, NY, an event renowned as the premier distance running race in the region. This captivating race, held annually on Labor Day weekend, offers runners a unique blend of historic charm and breathtaking natural beauty. Both the 13.1-mile half marathon and the 5K course wind through the National Historic Landmark District of Geneseo before extending into the picturesque Genesee Valley, where you'll pass ancient 300-year-old oak savannahs, serene sheep pastures, and idyllic horse farms. The half marathon features a course comprised of 40% paved and 60% dirt roads, with the majority closed to traffic, providing an immersive experience through rolling terrain that runners have noted offers a good challenge.

The Oak Tree Half Marathon is celebrated for its vibrant atmosphere and thoughtful amenities. Runners can anticipate live music along the course, historic aircraft flyovers, and unique, hand-made finisher medals for half marathon participants, creating an unforgettable race day experience. Seven aid stations on the half marathon course, five of which provide both water and lime Gatorade, along with ample restrooms and roaming first-aid personnel, ensure you're well-supported every step of the way. The 5K, which will host the prestigious USATF Niagara Open and Masters 5K Championships in 2026, offers a spirited tour through the village's historic streets, also featuring a water station and music.

Both races culminate with an exciting finish on the track at Geneseo Central School, where spectators can cheer you across the timing mats. Typical race day conditions in early September present pleasant temperatures, with highs around 77°F and lows near 53°F, and only a 12% chance of precipitation, creating ideal running weather. Beyond the personal challenge, participating in the Oak Tree Half Marathon directly supports local conservation efforts of the Genesee Valley Conservancy, making your miles count for a cause.
