From NYRR’s site:
Kick off the New Year at the Midnight Run! Join the fun and celebrate with dancing (starting at 10:00 p.m.) and a 15-minute fireworks show. With a countdown to midnight beginning at 11:59 p.m., the four-mile unscored run will begin on the stroke of midnight, as will a spectacular fireworks display to light up the night and the start of 2015.
I’ve never had the chance to participate in this run – mainly because I steer clear of Manhattan altogether on New Year’s Eve. But I’ve run Central Park countless times – late at night too. This run is probably a blast.
