Rhett's Run History

This challenging mountain bike course was designed by the 1996 Olympics key course designers. The trailhead is east of Antimi Baseball/Softball Complex in Cosmo Park. A large boulder marks the trailhead. The site for the trail is approximately 75 acres. The trail is 4.1 miles in length with the majority of it being constructed to a three-foot width. The trail is a memorial to Rhett Humfield Walters who was killed in a tragic motorcycle accident in April of 1996.

If you would like to host an event on the trail, please fill out a Park Special Use Application.
