The Oceans Seven is a marathon swimming challenge consisting of seven open water channel swims. It was devised in 2008 as the swimming equivalent of the Seven Summits mountaineering challenge. It comprises the North Channel, the Cook Strait, the Molokaʻi Channel, the English Channel, the Catalina Channel, the Tsugaru Strait and the Strait of Gibraltar.^[1]

The record for the fastest cumulative time for the completion of the 7 swims is held by Scot Andrew Donaldson, with a total swim time of 63 hours, 2 minutes.^[2]

The record for the fastest completion of all seven swims is held by Bulgarian Petar Stoychev who achieved it in 173 days, completing on 14 August 2024.^[3]
