The 44-year-old actor finished the 2.4-mile swim, 112-mile bicycle ride and 26.2-mile run in 15 hours, 30 minutes and 31 seconds. His individual times were swim, 1:45:00; bike, 7:11:56; and run, 6:06:22.

The star of the film "Rudy" crossed the finish line with his arms up in the air as the crowd chanted, "Rudy! Rudy! Rudy!" according to People magazine.

"This is an extraordinary challenge, and I like the idea that I am capable of leading an extraordinary life," Astin told the magazine in August about why he wanted to compete in the 140.6-mile triathlon.

He also raised over $25,000 for his charity #Run3rd, which supports running programs for underserved kids.

The day after the race, the "Goonies" star nursed his blistered feet and got some well deserved R&R.
