Today is National Roller Coaster Day, and we all knew Great Adventure was going to do something cool, but we had no idea they'd set a world record!

As part of Great Adventure's "Sleep and Soar" event, 167 riders set the world record for most roller coaster riders in pajamas!

The theme all summer has been the "DC Summer of Super Heroes." Participants spent one hour on BATMAN: The Ride to put themselves and Great Adventure in the history books.

Check out a recap of the action.
