Molli Serrano is determined to swim 2.4 miles, run 26.2 miles and bike 112 miles in the Ironman World Championship in October.
It has been 13 months since she had surgery for pancreatic cancer.
"It's a very aggressive surgery. I mean they took out half of my pancreas, half of my stomach, my gall bladder, part of the small intestine, the duodenum," she said.
A week after the surgery she was on a stationery bicycle. Serrano underwent six months of radiation treatments and chemotherapy, but she kept on training.
"My husband always says the doctors saved my body and the biking, swimming, running, and my friends and my support group out there saved my soul," she said.
She refers to her husband Juan as her "Can-cierge."
They have 8-year-old twins, who hope to be cheering for their mom in Kona, Hawaii.
To get in she entered a contest called "Kona Inspired" and made it to the final round.
"Basically what it is is ordinary athletes overcoming extraordinary situations," she said. "They're going to take the top two out of this round with votes. I'm very hopeful."
"It's really what's going to give her the victory she deserves," said her husband Juan.
Last week Molli was featured on the Today Show. Kathy Lee helped write a song about her titled "You Do the Impossible."
Voting ends on July 18 and she is in second place. They take the top two people. Click here for her page.
