About the Tidewater Strider Dismal Swamp 50K / Marathon / Half Marathon / 50K Relay
The course runs along the Dismal Swamp, flat and straight on an out-and-back route that attracts runners chasing Boston qualifying times. The terrain is smooth and consistent. Several distance options are available, from a half marathon up through a full and an ultramarathon distance, plus a relay format.
Packet pickup runs the afternoon before at a local running store, with race-morning pickup at the start line as a backup. Post-race, there is a beer garden and pizza on site.

The Tidewater Strider Dismal Swamp 50K / Marathon / Half Marathon / 50K Relay has been held every year since at least 2020. 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.
