Evansville resident Diana Holland has been a physical fitness instructor for 27 years.
On August, 31 she'll face her biggest physical test yet when she competes in the Ironman Triathlon competition in Louisville.
More than 2,500 men and women will be competing from around the country and around the world.
Since 2000, the 50-year-old mother of three has competed in some 80 triathlons: the Sprints, Olympic, and Half Marathon portions of the competition. But this is her first attempt at the full Ironman Triathlon.
Now in her peak phase of preparation, the longest and most strenuous portion of her training, she's been preparing about 15 to17 hours a week for a 2.4 mile swim, a 112 mile bike ride and a 26.2 mile run.
"I have no problems with the swim or bike, it's just the run," Holland said. "I am just not a real good runner, so I am going to run walk it, which is what all the guys did. After 112 miles on a bike, you don't really feel like running a marathon."
Diana will check in at Louisville on August 29. The competition is set for Sunday, August 31.
