About the Lock 2 Lock Marathon/Half Marathon/10k
The course runs along the C&O Canal Towpath, a packed-dirt path that traces the old canal through the Williamsport area. The terrain is almost entirely flat, with barely any elevation change over the full distance. All three distances share the same out-and-back route between a pair of historic canal locks, with marathoners completing the stretch twice. Aid stations are spaced generously, stocked with water, Gatorade, pickle juice, and chips.
The start area is at a canal lockhouse, but parking is elsewhere: two nearby lots serve the race, and runners walk a short distance in from there. Packet pickup runs on race morning near the start, and also on the two evenings before at spots in Hagerstown and Williamsport. A tarp near the start line lets you stage personal nutrition and gear for the race.

The Lock 2 Lock Marathon/Half Marathon/10k has been held every year since at least 2023. 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.
