HONOLULU (KHNL) -- Triathlons are one of the ultimate endurance tests for an athlete. Hundreds turned out early Sunday morning for one of the most picturesque races in Hawaii.
It's the crack of dawn on the east side of Oahu. The perfect backdrop for some racing.
"I think Lanikai is one of the best places to do a triathlon," said Marion Summerer. "Just the scenery, and the finish on the sand part is just, it's really unique."
It's the 7th annual Lanikai Triathlon -- a 500 meter swim, 20-K bike ride, and a 5-K run. The race is sanctioned by USA triathlon.
"The straight forward bike course, I really like that," said Summerer, who won the womens division. "The hill in the end, and the run course, it's just beautiful."
"It was maybe a little tougher than I thought it'd be," said men's winner Tim Marr. "But nothing beats some stiff competition and coming home with a win."
Marr finished in 53-minutes, 19 seconds -- a slim 19-seconds better than second place.
