On Sunday evening December 4, 2011, over 44,000 runners participated in the largest nighttime running event in the world, the Zappos.com Rock ‘n’ Roll Las Vegas Marathon & Half Marathon to benefit the Crohn’s & Colitis Foundation of America (Pictured above: Kate Gosselin with Las Vegas showgirls Mary Ann Foreman (left) and Tala Marie (right) – Photo: © Scott Harrison / RETNA/ www.harrisonphotos.com).

Local and regional bands performed at every mile, keeping the runners and spectators rockin’ from start to finish. In epic fashion, over seven and a half miles of the world-famous Las Vegas Boulevard was closed for the race, with the entire 13.1-mile half marathon course running under the neon lights of the Las Vegas Strip.
We have photos of celebrities who participated in the race and you can read the complete results here.
