About the Seabrook Island Half Marathon and 5k
The race runs through Seabrook Island, a barrier island community where the roads are quiet and the surroundings are mostly marsh and maritime landscape. Both distances share the area, and the course has the feel of a private island that briefly opens itself up. Age grading is part of the awards structure, which tends to reward people who show up to race rather than just finish.
Parking is off the island at a county park called Mullet Hall, and buses run from there to the start. The return trip works the same way, pulling from the finish area at Freshfields Village, where the post-race gathering happens on an outdoor village green. Packet pickup the evening before is at a Fleet Feet location, with race-morning pickup also available at the start site.

The Seabrook Island Half Marathon and 5k has been held every year since at least 2015. 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 Nov 12, 2026.
