Eastwood didn't undertake this major endurance event alone. He was also joined by a number of fellow actors, including Steven McQueen, Geoff Stults, Parker Young, Claire Holt and Bryan Greenberg.
They also joined model and triathlete Jenny Fletcher and former NBA pro Jason Collins after crossing the finish line.
While participating in the event, Eastwood documented his eagerness to help the cancer-stricken kids that the organization assists. In one video shared before the event, the 30-year-old actor can be seen warming up with some of his tri teammates. Eastwood, who’s sporting goggles for the race ahead, adorably gives the camera a growl.
Eastwood also posed with his competitors at sunrise, and yes, he and Stults are shirtless in this shot. You're welcome.
"Great morning with great people," he captioned the Instagram post. "Get out there and do one thing you've never done before.!!! It doesn't have to be big or time consuming. … It starts with one."
Eastwood frequently posts positive affirmations and encourages fans to get active on social media, and this event proved the perfect opportunity to do both. He continued the caption by musing, "We are only on this planet for a short time. It's easy to get caught up in the material things in life. But that isn't what life Is about. It's about how you touch people in a positive or negative way. It's your choice.”
His friend, Holt, took to Instagram after the event, posing with two adorable kids who had participated in the South Beach Triathlon Tot Trot. "Amazing day! Loved racing on behalf of little survivors like Chloe," the Australian actress captioned the sweet snap. "Can't wait to do it again."
Greenberg felt the same way about the event, sharing this post-race shot with Young and Holt.
If you're going to maintain a body as chiseled as theirs, you might as well lend a hand in the process! Another perk of aiding children in need? New friends. Eastwood's race partner was none other than a hog named "Peanut," which Eastwood was very happy about.
Just last week, Eastwood had a very different celebration -- his 30th birthday! Go inside the bash in the video below.
