NEW CANEY, Texas — The Big Rivers Splash & Dash, produced by Rad Racing Company, is adding an exciting twist for 2025: a sweat-activated race shirt that reveals hidden designs as runners take on the course.

Unlike a typical race tee, the Splash & Dash shirt hides a playful secret: the harder you run, the more the shirt reveals. With sweat-activated printing, hidden stars, mascots, and race patterns gradually come alive — turning every drop of sweat into part of the design.

The shirt evolves throughout the race experience:

● Dry Start: A clean, bold Splash & Dash logo.

● Light Sweat: Motivational graphics and hidden race elements begin to appear.

● Full Effort: The shirt transforms completely, unveiling a vibrant all-over design.

The concept is simple yet powerful: “The more you sweat, the more you get.”

By combining moisture-reactive technology with playful, hidden artwork, the shirt delivers both social media buzz and a lasting keepsake that participants will want to wear again and again.

“We’re thrilled to partner with Rad Racing on Splash & Dash,” said Ryan Zhu, founder of X T-shirt. “Sweat-activated shirts surprise runners in the best way possible — they celebrate effort and turn performance into a shared, visible achievement.”

The Big Rivers Splash & Dash takes place in New Caney, Texas, on Sat September 20. The event benefits the Tango2 Research Foundation, making every step a contribution to a greater cause. Registration is now open at: https://runsignup.com/Race/TX/NewCaney/BigRiversSplashDash.
