He won three gold medals in Beijing on his way to a knighthood; they consulted him when building the Velodrome; now Sir Chris Hoy can overcome Sir Steve Redgrave's haul of five golds to become Britain's greatest Olympian. Hoy takes place in the track cycling keirin event (he has a career record of 55 wins from 60 races) on a day that also sees Victoria Pendleton face her Australian arch-rival Anna Meares in the women's individual sprint, and Laura Trott go for glory in the exhausting combined omnium event. Brothers Alistair and Jonathan Brownliee go head-to-head in the men's triathlon in Hyde Park while Britain are favourites to win the equestrian dressage team final at Greenwich Park. In the Olympic Stadium, watch out for 20-year-old, Croydon-born Lawrence Okoye, who is taking part in the discus event two months before taking a place to read law at Oxford University. GB's Robbie Grabarz is also a medal hope in the high jump, while Australia's Sally Pearson is favourite to beat defending champion Dawn Harper of the US in the women's 100m hurdles. With windsurfing axed from the Rio 2016 Games, Britain's Nick Dempsey is hoping to grab a farewell medal at Weymouth and Portland but will face stiff competition from Dutchman Dorian van Rijsselberge. The first of two synchronised swimming medals – the women's duet event – is decided on Day 11 too.
