The Oak Tree Half Marathon is the premier distance running race in the region. Run through the National Historic Landmark District of Geneseo and head into the Genesee Valley past 300 year old oak savannahs, sheep pastures, and horse farms.

The course features spectacular scenery with a small town feel but includes all of the amenities you would expect at a big city race.

With live music on the course, historic aircraft flyovers, and hand-made finisher medals, the Oak Tree is a unique half marathon that showcases the beauty of the Genesee Valley.
