West Tyson County Park 131 N. Outer Rd East, Eureka, Missouri 63025 from I-270, take I-44 west for 7 miles to the Lewis Road exit. At the Lewis Road exit, make a right turn (north). The park entrance is on your right immediately after the exit. Start area is the near the entry gate to the park.


The race is run on the popular Chubb trail. The 25k will do one out & back & the 50k will do two. The 8 Mile race is new in 2023 and is intended to welcome new trail runners. The 8-mile race will head out on the same course with the 25/50K but is an out and back. A limited number of 8 Mile spots will be available to preserve the same amount of 25/50K slots as prior years . The trail itself varies from a gravel service road, to a mostly dirt trail along the Meramec river, to a mile-long series of climbs, to finally a rolling trail that winds through the hills of the Meramec River. There are no stream crossings. If the Meramec River is well above flood stage then the race will be rerouted. There are two railroad crossings and extreme caution must be taken because the trains come through this area at a high rate of speed. Runners may see deer, turkey and other wildlife throughout this trail run.


- Unfortunately there are no refunds if you can't make it. We utilize the money from registrations for all the race day activities. Additional money will be donated back to the trail system or organizations in the STL area that help make our trails beautiful
- You may drop from the 50k to the 25k up to two weeks prior to race day. Any drops after this or on race day are allowed, but you will not be eligible for awards (Overall or Age Group).
- Sorry no waitlist.

Bib Transfers

We will allow bib transfers until 3/20/2023. If you choose to give or sell your registration to another runner, it will be up to you to make that transaction. A bib transfer is a 2-step process that must be completed by the original registrant AND the recipient (not the Race Director).To complete a bib transfer, you must log in and edit your race registration on the UltraSignup website and enter the recipient's name and email address to set up the transfer; the recipient must then complete registration via UltraSignup using the credit created by your cancellation/transfer to enter the race. If someone shows up on race day and has not completed this process, they will not be entered in the race. If you are selling your registration to another runner, it is up to you to collect the money from the buyer. Funds will not be transferred via UltraSignup.


All finishers will receive a Medal, 4 Hands beer for post race libations, and all runners will receive something custom from BOCO Gear.
