Philippe Croizon (born 1968) is a French athlete and the first quadruple amputee to swim across the English Channel and to run the Rally Dakar.

[2][4] He began a regimen of swimming, training for over five hours per day with the Maritime Gendarmerie, the French marine police, in the sea near La Rochelle.

[2] Croizon's preparations for the channel-swim attempt took 35 hours per week for two years; throughout the training period, he received letters of support from national politicians, including then-President of France Nicolas Sarkozy.

[1] In April 2012, Croizon announced a new project, to swim four straits separating five continents, in which he would be accompanied by long-distance swimmer Arnaud Chassery.

[14] Croizon completed his Straits of Gibraltar crossing in July, from Tarifa, Spain, over 14 km (9 mi), to land near the city of Tangier, Morocco.

[17] When a lull in the bad weather arrived on 17 August, the team's start was delayed by high waves until the late afternoon (3 pm local time).

After crossing the International Date Line, they continued for a few hundred yards to Great Diomede island in Russian waters without official permission.
