Republic Tiger Tri

01/05/2026

After 19 amazing years, the Republic Tiger Tri and Youth Tigger Tri have officially crossed their final finish line. These two events will not be returning in 2026.

We’ve had a blast watching thousands of athletes swim, bike, and run their hearts out over the years! Whether it was your first triathlon or your one-hundredth, thank you for being part of something special.

There are so many individuals and businesses to thank, but we want to give our biggest thanks to our longtime presenting sponsor and friends at Larson & Miller Law Firm. Additional thanks go to Fleet Feet Springfield, Ozarks Multisport Club, Heartland Racing Co., and all the volunteers and supporters who made this event possible year after year.

While this triathlon chapter is closing, there is still plenty happening through Republic Parks and Recreation. We hope you’ll stay connected and join us for new programs, events, and opportunities in our community!
