Sao Paulo:

A 52-year-old man who swam the 5,265-kilometer length of the Amazon River was released from the hospital on Monday and recovering from health problems brought on by the 65-day swim, his son said.

Slovenian Martin Strel was hospitalized with high blood pressure and dizziness on Sunday immediately after completing the swim. Strel contended with exhaustion and delirium after the swim.

If confirmed by Guinness World Records, it will be the fourth time he has broken a distance swimming record.

In 2000, Strel swam the length of Europe’s 3,000-kilometer Danube River. He broke his own record two years later when he swam 3,798 kilometers down the Mississippi, and in 2004 he swam 4,000 kilometers along China’s Yangtze.
