The Annadel Half Marathon is a non-profit fundraising event to help build and maintain the trails in Annadel State Park.
The Half Marathon course is a hilly, and technical course designed for the experienced trail runner looking for a challenge. The 5K course is an out and back. All participants will receive a shirt, post race meal, and finishers medal! For more information visit our website.

We are partnering with Underfoot Runs to offer the Annadel 5K. Funds raised through the Annadel 5K race will help to build new trails at Taylor Mountain Regional Park.
