Vural Tandoğan, a 57-year-old swimmer who swam across the English Channel, the Catalina Channel and Manhattan Island leg and earned the triple crown of ocean swimming in the past, has been honored with another triple crown after completing a series of three different swims in Lake Tahoe, located in the U.S.

Turkish swimmer Kamil Alsaran, 59, passed the North Channel between Ireland and Scotland last year and won as the "oldest male swimmer" and "first Turkish swimmer" who completed this course.
