Chubb Trail Races

Chubb Trail Races are held April 3, 2027 at West Tyson County Park, 131 N. Outer Rd East, Eureka, Missouri 63025. Parking is available along Lewis Road.

The course follows the Chubb trail and varies from gravel service road to mostly dirt trail along the Meramec River. The route includes a mile long series of climbs and a rolling section that winds through the hills of the Meramec River. There are no stream crossings. Two railroad crossings are on course and require extreme caution because trains pass at high speed. If the Meramec River is well above flood stage the race will use a high water route. Runners may encounter deer, turkey and other wildlife.

Distances offered:

  • 50k
  • 25k
  • 25k RUCK
  • 8 mile

There are no refunds for registrations. Registrations fund race day activities and excess funds are donated to local trail systems or organizations. A runner may drop from the 50k to the 25k up to two weeks before the race; drops after that or on race day are allowed but are not eligible for overall or age group awards. There is no waitlist.

Bib transfers are allowed until approximately two weeks before the race and must be completed by both the original registrant and the recipient through UltraSignUp. All finishers receive a medal, plus beer and grilled food after the race; swag items are announced as confirmed. Visit the organization's website for the most recent information.
