Southend-on-Sea

Southend sits on the Thames estuary with flat seafront running along the iconic pier and promenade — the terrain never rises above 30m, making it ideal for speed work and marathon training. The nearby cycling scene is dominated by 10-mile time trials; the GP Neil Ord 10 and Gravesend CC Club 10 races draw serious cyclists from across Essex and Kent, with rolling courses inland around the Medway valley. Runners looking for varied terrain head 20km north towards Basildon or west into the Chilterns foothills.
