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 50K run is two out-and-backs on the popular Chubb trail. 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.

All entrants will receive a tee-shirt or other cool schwag. Belt Buckles for the 50K finishers, medals to 25K. Age group awards 18-39, 40-49, 50-59, 60+

Refunds – None

Waitlist – we do not run a wait list for this event. We overbook up front just like an airline does knowing that there will be runners that will be unable to make it for various reasons. Bib Transfers: Bib Transfers are not allowed. If for some reason you are unable to run no one else can run with your bib #. We have already overbooked the race so your bib # is really not keeping someone else from running.
