In the 2011 Fit Nation Triathlon Challenge , six selected viewers will participate in a six-month training program. Each will receive all the gear, training and nutritional support necessary to complete the race and will compete alongside Dr. Sanjay Gupta on August 7 in the Nautica New York City Triathlon.
Processed, sodium-filled, fatty foods and pop. That's what Anastasia Cirricione remembers about her nutrition growing up.
"I'm just a Midwestern girl that was raised on sugar and fried foods and pop," she said. "I came from a low-income family of six."
As a kid, she never participated in sports, partly because she was unfit, she says, but also because she was self-conscious and shy.
"I've looked in the mirror and cried at the reflection staring back at me. How have I let myself get like this?" she wrote in her iReport submission. "At 22 years old, I've decided I'm unhappy with the way I feel. I know I'm capable of better."
So, Anastasia threw her hat into the ring for the 2011 Fit Nation Triathlon Challenge and was selected in early January.
"This is something so wildly out of my comfort zone, I'm not even sure it's officially sunk in yet," she said.
But since she was selected, Anastasia has started running three to four times per week, doing yoga regularly, swimming and riding the stationary bike.
"I went for my first "swim" – 500M. It was humbling, for sure," she said. "Now, I just have to triple that!"
With the help of triathlon coach Dawn McPherson, and Fit Nation Athletic Director Laura Cozik, she says she's not worried at all about crossing the finish line.
"I feel confident knowing I have a great support and training team behind me, five other worthy teammates and ALL of the CNN followers to cheer me on."
And after a successful kickoff weekend in Atlanta with her teammates, she says she's even more fired up about the journey ahead.
"I'm tired, sore, and have a little bit of a cold, but my adrenaline is still flowing," she said. " I'm so excited to accomplish this!"
At the end of the day, Anastasia says this journey is for her.
"I deserve better, my body deserves better," she said. "I want to learn the proper nutrition to fuel my body. I want to push my body to physical tests it's never been challenged by before."
