Vincent is a best-selling author and the first woman to win "The Biggest Loser." After dropping 112 pounds on the reality show, Vincent is preparing to compete in her first Ironman Triathlon.
The Ironman is no easy feat. The grueling race consists of a 2.5-mile swim, a 112-mile bike ride followed by a full marathon.
Vincent is undaunted and ready to go. "I believe that we can do absolutely anything we want to do. We absolutely can if you have a plan and you train and you stay committed. And it's just literally one choice at a time, one step at a time," she said.
You can see if Vincent accomplishes her goal by tuning in to "Live Big with Ali Vincent."
The Ironman episode airs Saturday night on the Live Well Network at 5:30 p.m. You can find the Live Well Network on digital channel 7.2, and channels 195 and 715 on Comcast.
