Organiser's Description
PROCEEDS FROM THE RACE WILL BENEFIT THE UNION R-XI FOUNDATION.
Join us for the 48th Annual Founder's Day Run presented by the Union R-XI Foundation. Since the Union R-XI Foundation took over this event, 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.
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 live music. Founder's Day is an annual family-friendly event and takes place at the courthouse square in downtown Union, MO. 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 a cornhole tournament, 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/.
