The Lincoln Tunnel Challenge 5K is one of the most unique races in the country. This USATF certified 5K (3.1 miles) takes place mostly underwater and spans two states. The toll booths in Weehawken, NJ mark both the start and finish of the race. There is a cone turnaround once participants reach the NYC side of the tunnel. All proceeds benefit Special Olympics New Jersey and the over 22,000 athletes and Unified Partners.
