A man died trying to swim across the River Thames as a bet, an inquest heard.
Peter Redding, 34, from Tilehurst, Reading, attempted to cross the river near Henley bridge after taking up the £200 wager.
Oxford Coroner’s Court heard how although the bet was quickly withdrawn, Mr Redding took off his clothes outside the Angel on the Bridge pub before entering the river.
Friends noticed him struggling about half way across the river before he disappeared from view. His body was recovered the following morning.
Mr Redding had been drinking cider, champagne and tequila on the night out with colleagues from Audi Reading in July last year.
A toxicology report showed levels of 160mg of alcohol per 100ml of blood, more than twice the drink-driving limit.
Coroner Nicholas Graham recorded a verdict of accidental death.
