Semi-Marathon de la Grosse Pomme

Semi-Marathon de la Grosse Pomme, the NYCRUNS Big Apple Half Marathon, is run in New York City on December 12, 2026, over a single distance: the half marathon (13.1 miles). The route stays largely inside one of the city's big public parks, so you get the New York atmosphere and the skyline in the distance while running mostly on quiet, tree-lined roads.

A park-based half is a forgiving setting for a December race: the road surface is consistent, and you pass the same landmarks more than once, which makes pacing easy to judge. If this is your first half marathon, give yourself a 16-week build with one long run each week; if you are chasing a time, the repeating scenery makes it easy to know what each mile still has in store. Plan your layers for a December morning and leave one behind before the gun.
