Union Founder's Day 10K | 5K

Proceeds from the race will benefit the Union R-XI Foundation.

Join us for the 47th Annual Founder's Day Run presented by the Union R-XI Foundation. Under new direction, the race has returned to its roots with an evening start during Union's annual Founder's Day Festival. Being the oldest and longest-standing road race in Franklin County and one of the oldest in the St. Louis metro area, the Founder's Day Run has been known to be a tough race. This year will be no different. The start/finish has been moved to the courthouse square.

Come early and bring your family to see what Founder's Day has to offer. Then after you finish your race grab yourself a FREE beer (21 and over) and stick around and enjoy some music. Founder's Day is an annual family-friendly event and takes place at the courthouse square in downtown Union. The celebration is sponsored by the Union Parks & Recreation Department and local businesses with the primary goal of bringing our community together to celebrate our great city. The festivities include turtle races, craft vendors, a cornhole tournament, pickleball tournament, pie baking contest, food trucks, music, and more.

The Union R-XI Foundation is a 501(c)(3) tax-exempt nonprofit, charitable organization that supports the students, staff, facilities, and programs of the Union R-XI School District. To learn more about the Foundation please visit https://www.rxifoundation.org/.
