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.
