The Seacoast Half Marathon runs along the New Hampshire coast out of Portsmouth. The organizer's description leans heavily on the cause rather than the course, so the terrain and route shape aren't detailed here. What is clear is that the race has a long history in the region and is tied to a local nonprofit, with fundraising built into the registration process.

The Seacoast Half Marathon has been held every year since at least 2006. That is as far back as RunSignup's records for this race go, so it may well be older.

How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 25, 2026.
Almost certainly not. Half the 13.1 Miles field finished slower than 2:04:33, and the last recorded finisher came in around 3:57:54, so there is a long tail of runners behind the middle of the pack. Most fields are far slower than people expect.
With 943 finishers there are runners at every pace, so you are never out on your own. There is no qualifying time, and the finish-time spread above shows how varied the field really is. If it is your first 13.1 Miles, that spread matters more than the winner's time.
The 13.1 Miles winner ran 1:11:19 while the median finisher took 2:04:33. That spread points to a mixed field, with a competitive front and a big recreational middle.
