Celebrate spring at Camp Ondessonk’s Spring Fling on April 11, a fun-filled day that combines our annual trail races with an open house for families and visitors of all ages.

The day begins with runners hitting the trails for the 16th Annual Ondessonk Trail Races. Whether you take part in the challenging Half Marathon, scenic Manchester Trail 10K, classic 5K, or the One-Mile Fun Run, there’s something for participants of all ages and abilities. Each race showcases the natural beauty of Camp Ondessonk in full spring bloom, making it a memorable experience for seasoned runners and casual participants alike. Awards will be given to top male and female finishers in select races, and all registered runners receive a commemorative T-shirt. Please visit our page on the RunSignup website for more information and to register.

In the afternoon, guests are also invited to enjoy our Open House, offering guided tours of Camp Ondessonk, opportunities to explore favorite Summer Camp activity areas, and time to connect with our friendly camp staff. Online registration is optional but appreciated to help with planning.

Whether you’re curious about Summer Camp programs, looking for a great family outing, or cheering on race participants, the Spring Fling offers something for everyone.

Join us for a day of outdoor adventure, community, and discovery. Run the trails, explore Camp, and experience the Spirit of Camp Ondessonk this spring!
