About

Harborside Half Marathon & 5K takes place in Newburyport, Massachusetts, on November 8, 2026. The half marathon (13.1 miles) starts at 9 a.m. and the 5K at 9:15, on a route through classic New England scenery in the middle of fall. The morning ends with a post-race celebration serving pizza, snacks and craft beer for those of legal drinking age.

A late-morning start is unusual and genuinely useful: you can eat a normal breakfast, warm up without rushing and still be finished by lunch. On the road side, the half rewards a 12-week build with one long run a week and a couple of steady-effort sessions at goal pace, while the 5K works as a hard, honest test of current fitness. Runners doing both distances across a season often use an event like this to sharpen speed before turning to a longer winter target.
