NYCRUNS Big Apple Half Marathon

NYCRUNS Big Apple Half Marathon is held in New York City on December 13, 2026. Two distances are on the program: the half marathon (13.1 miles) and a 5K, both organized by NYCRUNS, which puts on races throughout the city across the year.

A half marathon in the middle of December is a natural end point for a fall training block, and a useful stepping stone if a spring marathon is your real goal. Give it 12 to 16 weeks with one long run each week reaching 11 or 12 miles, plus a weekly tempo effort at half marathon pace. The 5K is there for anyone who wants the same morning without the mileage. Whichever you enter, plan your layers for a December morning and drop one before the gun.
