COEUR D'ALENE, Idaho -

A Utah woman diagnosed with leukemia is among the 2,600 athletes set to compete in Ironman Coeur d' Alene this weekend.

Alayna Williamson and her husband, Troy, both signed up for Ironman Coeur d' Alene shortly after she was diagnosed with leukemia in 2012.

"A little over a year ago I found out that I have cancer and then it was just, you know, you can't live for next year or next week or even tomorrow.  You have to do what you want to do when you know you can do it," Alayna Williamson said.

"So far have been able to stay healthy enough that I haven't had to go through chemo.  So they just tell me that when I do, the stronger I am, the better I do through the treatment," she added.

Over the past few months, Williamson and her husband have been training non-stop.  And, this week the couple drove up from Salt Lake City with their four kids for the race.

"I'll be really happy to cross that finish line," she said.

Williamson's husband said he will be thinking about her constantly on race day.

"It's a double whammy for me because I'll be out racing.  But the other time, I'll be thinking of her,  hoping that she does what she needs to do to finish this thing because this is her dream," Troy Williamson said.

The couple hopes their story will inspire other people to fulfill their dreams and to live each day to the fullest.

"I think you need to do what you want to do,  when you can and there's no better time than now.  If you wait until tomorrow there might not be that chance," Alayna Williamson said.
