<P> Jackie Cobell had intended to make the 21 - mile ( 34 km ) crossing by a more direct route in July 2010 , but inadvertently set the record for the slowest solo swim , when strong currents forced her to swim a total of 65 miles ( 105 km ) in 28 hours and 44 minutes , breaking the record set by Henry Sullivan in 1923 , who had been the third person , and the first American , to make the crossing . </P>
