The furthest a person has swum without assistance from a machine is approximately 110 miles. This record was set by Benoît Lecomte in 1998 when he swam across the Atlantic Ocean from Massachusetts to France.
They walked across the ocean on the scum left from when the Germans swam here.

If you are referring to te Ben Lecomte that swam across the Atlantic and is training for the swim across the Pacific now, he's 45.
No one has ever swam across te longest river
Zero. If you actually understand that it is seriously impossible to swim for that long without drowning, dehydrating, or being devoured by sharks, then you can see that no one has swam across the Pacific ocean. The greatest distance ever swum by a person is supposed to be when Benoit Lecomte "swam the Atlantic Ocean". Note, however that since there is no standard definition of the feat "swimming across the Atlantic", there is uncertainty about the distance that Lecomte actually covered swimming in the water rather than riding in a boat. He only swam for 6-8 hours each day, so he would have been on board a boat the rest of the time. Also, it should be noted that he stopped for a week in the Azores near the end of his swim. It is unlikely that he actually swam the whole distance; according to the Rocky Mountain News, Lecompte would have had to average 8 mph to have swum the entire distance, 3-4 times as fast as other long-distance swimmers. Lecompte announced that he plans to "swim the Pacific" in 2012. As of February 2012 the planned date for the start of the swim is 14 April 2012.
