Eliza Dushku: Triathlon Terrific

Posted Monday April 12, 2010 12:31 PM GMT

Taking on one of the biggest challenges an athlete can face, Eliza Dushku competed in a mini-triathlon over the weekend in Miami, FL.

The “Open Graves” actress along with boyfriend Rick Fox took part in the third annual Nautica South Beach Triathlon on Sunday (April 11).

The competitive race which includes a half-mile swim, 19-mile bike ride and four-mile run benefits the St. Jude Children’s Hospital.

Shortly after, the 29-year-old star tweeted, "I feel like I ate the SUN! My body's burning up right now. We finished 2hrs45mins. @rickafox came in 1st place in male celeb division!" (Oddly enough, Mr Fox was the only one in that category).
