Marathons in Southend-on-Sea 2026 - 2027

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

The seafront promenade is the spine of marathon training in Southend. It runs flat and uninterrupted along the estuary, and you can cover serious mileage without doubling back too many times. For something off the seafront, Hadleigh Castle Country Park to the west has trail paths with more variety underfoot - it hosted the mountain bike events at London 2012, which gives you some idea of the ground. Priory Park and Southchurch Park fill in the gaps when you want a shorter loop closer to home. Not quite ready for the full thing? Half marathons in Southend-on-Sea are a good place to find out.

Browse the listings below. The flat seafront makes pacing straightforward on race day, though the promenade can get busy. 10K runs in Southend-on-Sea and 5K runs in Southend-on-Sea are listed if you're still building up.
