Head to Sea Isle City, NJ for this 10-mile island run featuring roughly 2.5 miles on the boardwalk and the rest on the beach. You can register online through July 31st with early bird pricing ($30 individual/$35 team) available until July 25th, or sign up race day (August 1st) at beach patrol headquarters on 44th Street between noon and 5 PM—just bring cash or have Venmo ready, as checks and credit cards aren't accepted. Keep in mind that entry fees are non-refundable regardless of circumstances, and plan for extra travel time due to weekend traffic.
