The Marathon Swims, London’s marathon of swimming, returns to the London Aquatics Centre, on Queen Elizabeth Olympic Park on Saturday 8 November 2025. After sell-out events since 2017, the event is back to challenge swimmers to take on the ultimate swimming challenge, a Marathon 10k.
The ballot for places in the Half Marathon 5k and Marathon 10k, are open from 19 February. The event also includes the 1k Challenge and the Team 10k, where teams of 2 take on the 10km distance between them, which go on general sale from 19 February.
Marathon Swims continues its partnerships with Alzheimer’s Society as the charity partner and venue partner Everyone Active. All entries to Alzheimer’s Society places are offered at HALF Price and are on sale a week earlier from 12 February 2025.
