We hope you join us in 2027 for one of Chubb Trail Races. This event is for newbies to expert level trail runners. We have a race for everyone. Bring your road running friends with you and let them fall in love with the trails. Between the challenging trails, good food, and live music you will be glad you signed up! Believe me, this race will not disappoint!
The ruckers and runners will follow the same 25K course. Participants must carry a minimum of 20 pounds (not including food and water) for the entire race. Ruckers can carry a backpack, weighted vest or rucksack. All packs will be weighed at the start of the race. Whether you’re an experienced rucker or ready to try something new, this challenge will test your endurance and grit. All participants will earn a finisher’s medal for completing the course.
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.
Packet pickup will be Friday, April 2, 2027, at the Des Peres Fleet Feet location at 4:00 pm - 6:30 pm. Race Day pickup will start at 7:00 am at the entrance of the park.
We have a nine hour-ish cutoff for all races. We are a relaxed group! For 50K racers the cutoff for the first loop is the 4 hour-ish mark.
Lots of aid stations throughout the course. They will have standard ultra food (bananas, pretzels, potatoes, chips, water, electrolytes.) This is a cup free race so make sure you bring your own water bottle or hydration pack to refill at the aid stations. Aid stations will be set up approximately at 3.5M, 8M, 12.5M, 16M, 19.5M, 24M and 28.5M. It is always a good idea to carry food and water in case we have a very hot day.
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 a week 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.
We will allow bib transfers until 03/31/2027. 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.
We will have a tarp laid out right when you walk into the park on the way to the start line. It is a good idea to put your NAME and RACE NUMBER on your bag. We will move these bags to the finish line, which is also halfway through the 50K. All drop bags must be picked up before leaving the race. All unclaimed items will be donated to charity.
We are still working on the swag for the 2027 race. We will keep you posted!
