Description
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:
- Aquathlon (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.

WEATHER & CANCELLATION/REFUND POLICY
In the event of inclement weather, the start time of this event may be delayed by up to 1 hour. Past this time, the even course may be shortened or altered to protect the participants. This event proceeds rain, shine, snow, or cold. For that reason, we have a strict no-refund policy.
If conditions turn unsafe, the event may be cancelled. Event changes and cancellations are at the discretion of the Race Director.
We always strive to produce a full and safe sporting event, but sometimes the weather conditions can affect those plans.
Considerable amount goes into planning a sporting event and we do so with the best intentions. Unfortunately, no one can control the weather and race directors are not the exceptions.
Our goal is to always produce a full event as scheduled and only modify these plans due to safety concerns some of which can be caused by weather conditions.
If you are unable to participate in the event, upon request we can switch you to Virtual and you can still receive your packet, shirt, and medal, and you simply run the race on your own time on your own course. *See our virtual race information for complete details.
Thank you for your understanding of these policies and we appreciate your participation.
