Big Rivers Waterpark proudly presents... the 2nd Annual Big Rivers Splash & Dash — Benefitting the TANGO2 Research Foundation! Lace up your sneakers and get ready to make a splash for a cause that hits close to home. Join us Saturday, June 13th 2026 for the Big Rivers Splash & Dash, where every step you take supports critical research and awareness for TANGO2 — a rare genetic disorder that’s personally impacted the Galland family, owners of Big Rivers. There’s a race for everyone: - Duathlon (500m Swim & 5K Run)
- 10K Dash
- 5K Dash
- Kids Dash (10 & Under)
- Virtual Runs (for those that can't make it & our long-distance supporters!) 
The scenic course winds through Big Rivers Waterpark and around our picturesque lake, giving you a unique view of the park. Expect fun, energy, and excitement at every turn — with the added reward of supporting a truly meaningful cause. Why We Run:
The TANGO2 Research Foundation was a lifeline for Megan Galland, who faced her first health crisis at just six months old during a family trip. Initially misdiagnosed, Megan eventually received answers thanks to the tireless work of the TANGO2 Foundation. Now, we're running to give that same hope to other families.
