About the GREAT SOUTH BAY RUN
The courses start and finish at a marina park, with the longer routes winding through the historic downtown area and past residential neighborhoods near lakes, canals, and waterways. The finish line opens up to an unobstructed view across the water toward Fire Island, which makes for a strong ending regardless of how the rest of the run went.
Packet pickup runs the evening before the race at the marina park, with race-morning pickup available at the same spot. Parking for race day is in the boat launch and beach car parks nearby, but it closes before the last wave goes off, so arriving early matters.

The GREAT SOUTH BAY RUN has been held every year since at least 2016. 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.
