Sea to Star Cycling Expedition

HONOLULU (HawaiiNewsNow) - The Sea to Stars cycling expedition is the hardest cycling hill climb race in the world.

Those up for this epic life-changing challenge will depart from the oceanfront Mauna Lani Bay Hotel & Bungalows and cycle to the top of Mauna Kea Volcano.

The 2011 Sea to Stars cycling expedition takes place Saturday, August 13 at 9 a.m. Mike Zagorski won the race last year and is coming back to defend his title.

Cyclists will ride a distance of around 49 miles and climb to 9.300 ft elevation with a steepness grade of more than 17%.

Mauna Kea earns the distinction of the world's tallest mountain from the sea floor (30,000 ft tall), higher than Mount Everest which stands at 29,000 ft. Check out the video!
