Shia LaBeouf, Sean Astin, Gordon Ramsay, Audrina Patridge Finish L.A. Marathon

Transformers star leads celeb participants running 26 miles for various pet causes

Nobody walks in L.A., but they sure do run.

Nearly 25,000 runners hit the pavement early Sunday morning for the 25th annual Los Angeles Marathon. Among the celebs participating in the 26.2-mile trek from Dodger Stadium to the Santa Monica Pier were Shia LaBeouf, Lord of the Rings star Sean Astin, Hell's Kitchen overlord Gordon Ramsay, The Bachelor's Andy Baldwin and Hills star Audrina Patridge.

Baldwin, an Ironman triathlete and an officer in the United States Navy, finished first among the celebs at 3 hours 24 minutes. Ramsay clocked in at 3:36; LaBeouf, running on behalf of veterans, crossed the finish line in 4:35; and Astin made it at 5:16. Patridge, running for a children's charity, tweeted after she finished and later announced that she "inhaled a philly cheese steak" postrace, but her time was not immediately available.

Meanwhile, celebs such as Julia Louis-Dreyfuss and Dwayne "The Rock" Johnson were among those cheering from checkpoints along the route.
