The star of the upcoming Baywatch reboot hit Zuma Beach on Sunday to compete in the 30th Annual Nautica Malibu Triathlon.

We can't remember the last time we saw a picture of Zac Efron where he wasn't at the beach.

The star of the upcoming Baywatch reboot hit Zuma Beach on Sunday to compete in the 30th Annual Nautica Malibu Triathlon. And because one Efron is never enough, he enlisted his little brother, 24-year-old Dylan!

"Racing for @ChildrensLA with the TEAM #NauticaMalibuTri," Zac wrote alongside a photo with Dylan and Olympic swimmer Conor Dwyer.

Lest you think starring in Baywatch alone was enough training for the event, he tweeted a pic on a bike ride just last week and captioned it with wave emojis.

Turns out the triathlon was in support of two good causes: the Children's Hospital (objectively the better cause) and giving us this picture of Zac dressed in spandex. (A good cause nonetheless.)

The event included a half-mile swim in the ocean, an 18-mile bike ride and a four-mile run...

So the brotherly celebration at the finish line was well-warranted.
