The vision for the Ondessonk Trail Race event came to trail runner and Camp Ondessonk alumnus Tim Slape on a Labor Day morning in 2010. He was not at Camp for the annual Labor Day Friends Weekend, but on his home running route in St. Louis with Ondessonk on his mind. In the spirit of promoting healthy and active lifestyles, Tim thought about how he could bring his joy for trail running together with the place he and so many others loved. Tim envisioned introducing people to the beauty of Ondessonk’s natural wonders by inviting them to run its trails. Tim envisioned creating an event that would not only promote wellness in celebrating a connection with the great outdoors, but would also bring outdoor enthusiasts together to support Camp Ondessonk. Out of this vision, the Ondessonk Trail Races were born.
