Big Rivers Waterpark proudly presents... the 1st 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, September 20, 2025 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.
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.
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.
HUGELY DISCOUNTED + EARLY ENTRY: to Big Rivers Waterpark & Adventures!! (race day ONLY)
Join us for a race that’s more than miles — it’s a movement. Let’s Dash for Discovery, Splash for Support, and Run with Heart.
