CAPTIVA ISLAND, Fl. - Swim, bike run.  That was the challenge that hundreds of triathletes conquered Saturday on Captiva Island.  It was the Third Annual Galloway Captiva triathlon.

"As someone who doesn't run, I don't swim and I don't bike so I figured, why not do a triathlon," laughs Jason Evers.

Whether it was their first race or well past their 50th...

"I probably have done 150," says Rick Miller.

Hundreds of athletes from all over the country gathered at the South Seas Island Resort for the third annual Galloway Captiva Triathlon pushing their minds and bodies to the limit.

The race started with a quarter mile swim through the Gulf, triathletes then traded their swim caps for helmets and rode ten miles on their bikes around the island.  But no matter the skill level, they all seem to have one thing in common.

"The most challenging is always the run, it just flat hurts," Miller adds.

"The run is always the hardest, you're just gassed at that point," adds Amy Barton.

With the first triathlete crossing the finish line at just 50 minutes, others are just happy to put a personal best in the books.

"This was my second year out here, I beat my time by about ten minutes and I didn't fall over this year," says Rick Barton.

It's a lifestyle you know we adopt a real healthy lifestyle and we train together and it ends up being a wonderful way to live," adds Miller.

A lifestyle first timers are quickly getting hooked on.

"You see some of these people that are 70, 80 years old doing it and I just say it's awesome and  think it's addictive," Evers adds.

Many of those athletes told us they were running in honor of a big name in the triathlon world.  Dean Davis was a world champion in the sport and played a big role in bringing triathlon to Southwest Florida.  

Davis was killed just last week while on a bike trianing ride.  Some of the runners Saturday wrote his name on their arms as a way to remember him.

"He was training for the national championships and he was kind of the first guy that put triathlon on the map here and it's a sad time so we raced in his honor," says Rick Miller.
