"I'm planning a lot of events to keep myself active," Biggest Loser season 8 finalist Rudy Pauls told In Touch recently — and he wasn't kidding! Rudy joined fellow contestants Danny Cahill and Rebecca Meyer, along with season 5's Ali Vincent and Mark and Jay Kruger to run the Boston Marathon on April 19. The race was not only an impressive accomplishment for their own fitness, but also benefited the charity Good Sports, which promotes healthy lifestyles among disadvantaged youth by providing them with athletic equipment and apparel. It was the second marathon for Danny, who ran his first in last season's finale, including the last 13 miles with his wife, Darci. On the way, they saw the perfect spot in Malibu for their vow renewal in September. The couple had just spent a romantic weekend planning their big day in New York, where they participated in an exclusive In Touch photo shoot at David's Bridal — although Darci still joined Danny in training. "We were running down the West Side Highway, and I said 'A year ago, we were prisoners. Our world was so small and now our world is so big — not just because of the opportunities, but because physically we can do things that we couldn’t before,'" Danny tells In Touch.
