Six Flags Great Adventure's Polar Coaster Challenge is Saturday, December 7 and a bunch of brave Jersey Shore souls are going to be taking part.

First, what is the Polar Coaster Challenge? Great Adventure is daring guests to ride Nitro wearing just tank tops and shorts in the frigid weather. As of this writing, the high on Saturday is expected to be 38-degrees.

Remember, Nitro reaches speeds of 80 mph and hits heights as high as 230-feet.

The event is to benefit Special Olympics New Jersey.

While all guests are invited to participate, here are the Jersey Shore residents who have already stepped up.

Leah and John Emmons

Nurse Leah and her husband John, from Brick, have taken the Polar Plunge with Special Olympics and want to raise awareness for those with special needs.

Jessica Geneski

Bayville resident Jessica Geneski is battling neurofibromatosis and wants to challenge herself on her favorite roller coaster.
