Hampton Half Marathon & 5K

Hampton Half Marathon & 5K runs in Hampton, New Hampshire, on March 7, 2027, with both the half marathon (13.1 miles) and the 5K going off at 10:00 a.m. The route follows the coast along Hampton Beach, and the organizers bill it as one of the flattest and fastest courses in the country, with ocean views for most of the way.

Flat and coastal is exactly the profile you want for a time goal, so this is a race built around personal bests rather than sightseeing. Experienced runners use it to sharpen a spring half, and the 5K gives newer runners a first finish line on the same ground. Because the terrain gives you nothing to hide behind, come in with your goal pace rehearsed: a 12-week block with weekly threshold work and a long run out to 10 or 11 miles fits the job.
