Field day gets an upgrade at the Grown Up Cup, Boerne’s outrageous adult competition returning Friday, June 27, 2025. Teams of four to six adults will battle it out through a series of wacky, laugh-out-loud games and activities designed to test agility, creativity, and a sense of humor.

Expect to find yourself flipping cups, sliding through giant slip-and-slides, shaking ping pong balls from a strapped-on box, racing in human wheelbarrows, playing oversized beer pong, and taking on plenty more ridiculous challenges. Whether your team dominates the field or takes home the prize for most epic fail, this one-of-a-kind event promises serious fun and unforgettable moments.

Registration opens soon, and spots fill quickly. Start planning your team and team name now for the ultimate adult field day showdown.
