THE American twins who sued the founder of Facebook, claiming he stole their idea, will take part in tomorrow's Fuller's Head of the River Fours.
Tyler and Cameron Winklevoss claimed Mark Zuckerburg pinched the idea for the hugely popular social networking site when they were pals at Harvard University.
The two parties reached a settlement, thought to run into millions of dollars, last year, before the twins went on to reach the rowing pairs finals at the Beijing Olympics.
They will be two of many British and foreign international rowers on display in the race, which starts on the Thames at Chiswick Bridge.
In all, about 550 crews, ranging from junior to elite, will take part, involving just under 2,500 oarsmen and women. Crews from across London and Surrey, and further afield, will compete for prizes across 21 different classes.
Seven of the clubs taking part are from Chiswick - Barnes Bridge Ladies Rowing Club, Cygnet Rowing Club, Mortlake Anglian & Alpha Boat Club, Quintin Boat Club, Thames Tradesmen Rowing Club, Tideway Scullers School and University of London Boat Club.
Tideway - featuring New Zealand, Great Britain and Slovenian Olympic rowers Mahe Drysdale, Alan Campbell and Iztok Cop - will be out to win the elite quad sculls title they won last year.
Campbell warmed up for the event by winning the Wingfield Sculls last week, beating team-mate Drysdale by three lengths.
The route taken will be the reverse of the Oxford-Cambridge Boat Race (both the 2010 Oxford and Cambridge crews will be on show for the first time), and so will start at Chiswick and finish in Putney.
It will be a useful exercise for the Winklevoss twins, who could row the route the traditional way next April after being picked for Oxford's Varsity Race squad, which will be whittled down to the final line-ups in the new year.
Tomorrow's race will begin at 1.30pm, with free views for spectators along the whole route.
It will be the 55th year the event has been held, and the 30th time it has been sponsored by Fuller's.
The racing will take on the form of a time trial, with crews setting off 10 seconds apart and timed over the 7km stretch of river.
The Thames will be closed up to Brentford Docks from 12.30pm to accommodate the event.
