Leigh-on-Sea 10K Classic
The Leigh-on-Sea 10K Classic takes place on Sunday 5 July 2026 at Leigh Marina, Leigh-On-Sea, Essex. Organised by Mammoth Events, the event is a 10K road race that starts and finishes at the marina and follows a coastal seafront route.
The course is described as fast and flat and runs along a scenic stretch of coastline. Race services include chip timing, an aid station, marshals and clear course marking, baggage drop and toilets, plus a bespoke finisher medal. There is an event village at Leigh Marina with music and a race-day atmosphere intended to provide visible support for participants and spectators.
The event is presented as open to a range of abilities. Practical information notes there is no parking at Leigh Marina itself; paid public car parks are available within a five minute walk and additional street parking exists in surrounding roads. The nearest station is Leigh-on-Sea, approximately a 10 to 15 minute walk from the marina. Final event information and race-day instructions will be provided to registered entrants before the race.
