Half Marathons Found In Southend-on-Sea

The most comprehensive list of half marathons in and near Southend-on-Sea in 2026 - 2027. Find your perfect race!

The esplanade gives you enough flat, uninterrupted miles to cover a half marathon distance without turning back more than once, which makes it well-suited to the longer training runs. The wind is the variable; a headwind makes the return leg significantly harder, and on an exposed day the effort required is higher than you’d expect. Priory Park and Southchurch Park are both sheltered options for when you want to take the weather out of the equation. Build up with 10K runs in Southend-on-Sea before stepping up to the half.

Have a browse through the listings below. The Hadleigh Castle Country Park trail heads out of town onto hilly, off-road ground and gives you a harder session when that's what you're after. Marathons in Southend-on-Sea are there when you're ready to go further.
