Bulgarian open water swimmer Petar Stoychev swam the Molokai Channel in Hawaii. ''From dark to dark! I swam the most difficult and longest channel of the Oceans Seven swimming challenge. The Molokai Channel in Hawaii is 45 km long. I started the swim at 3:01 a.m. from Kepuhi Beach on the Island of Molokai. I swam the distance in 18 hours and 53 minutes and finished at 9:54 p.m. on Makapu'u Beach in Oahu." In the final 10 km, Stoychev battled a strong headwind pushing him away from the shore.

Stoychev has conquered 4 of the Oceans Seven marathons - the English Channel, the Cook Strait, the Strait of Gibraltar and the Molokai Channel. He is yet to swim the North Channel between Ireland and Scotland, the Tsugaru Strait in Japan and the Catalina Channel between Santa Catalina Island and Los Angeles.
