Shia LaBeouf Running Los Angeles Marathon -- PICTURES

Shia LaBeouf keeps it sexy in a pair of running tights as he races in the Los Angeles Marathon on Sunday morning (March 21).

At 7:48AM, the 23-year-old actor started off his run at Dodger Stadium. Shia finished his 26.2-mile trek to Santa Monica Pier in 4 hours and 35 minutes. He placed #5825 out of nearly 25,000 runners. (#1 runner Wesley Korir ran the marathon in 2:09.)

FYI: Shia ran for veterans on behalf of U.S. VETS, which was emblazoned on his tanktop. (His dad fought in Vietnam.) He also wore CW-X Conditioning Wear Tights.
