You saw on tv a couple years ago a competition where Shaun White and other professionals had to surf skateboard and snowboard each other - what was it called?

The competition you’re referring to is likely "The Ultimate X Games," which featured various extreme sports, including Skateboarding, Snowboarding, and Surfing. Shaun White, along with other professional athletes, showcased their skills in a multi-discipline format. While it may not have been a specific event solely focused on competing against each other in all three sports, the X Games often highlights such cross-discipline showcases.
