Triathlon's wonder brothers Alistair and Jonny Brownlee have dominated their sport in recent years and finished first and second, by some distance, in the recent World Cup event in Switzerland.

With the home advantage of Hyde Park and a domestique in Stuart Hayes to help them, the brothers will be a daunting prospect for the likes of Spain's Javier Gomez, Russia's Alexander Bryukhankov, South Africa's Richard Murray and Germany's Steffen Justus.

The final night of action at the velodrome could be an emotional affair as it will be the last time track cycling's biggest stars, Sir Chris Hoy and Victoria Pendleton, compete together for Great Britain. Hoy will attempt to win the sixth gold medal of his stellar career in the keirin (heats - 10:00; final - 17:57), while Pendleton goes for a third gold in the individual sprint (semis - 16:00; final - 17:26) before retiring. German Kristina Vogel, China's Guo Shuang and perennial rival Anna Meares of Australia stand in her way. Britain's Laura Trott also goes for gold in the women's omnium (3km individual persuit - 10:19; 10km scratch race - 1607; 500m time trial - 1653). Trott is joint leader on 12 points after day one following her victories in two of the three disciplines at the velodrome.

Among the finalists at the Olympic Stadium, Grabarz has every chance of battling for a medal in the high jump and Lawrence Okoye made the discus final in dramatic style, while fellow Briton Tiffany Porter goes in the 100m hurdles semis (19:15) along with the brilliant Australian Sally Pearson. Usain Bolt will begin his charge for the sprint double in the morning (11:50) with the heats of the 200m, while Britain's Phillips Idowu will hope to overcome his fitness worries to qualify (10:45) for the triple jump final.

Britain's dressage team of Carl Hester, Laura Bechtolsheimer and Charlotte Dujardin are on the verge of making history in their sport. They hold the lead going into Tuesday's final round of the team event, narrowly ahead of Germany. A win would be a first Olympic title for Britain having exploded on to the sport's world-class scene with a succession of talented riders, the latest being Dujardin on Valegro, who set an Olympic record score last week. The 18 best-placed individuals will qualify for Thursday's individual final: the grand prix freestyle.

Dempsey and Bryony Shaw reach their medal races - possibly the last-ever windsurfing races at an Olympics, with the sport set to be replaced by kiteboarding for Rio 2016. Dempsey lies in silver medal position going into the decider, with the gold already secured by Dutchman Dorian van Rijsselberge, but Bryony Shaw will struggle to match her bronze from Beijing as she is down in seventh place (14:00).

  • HOCKEY (19:00-20:30): GB men

Great Britain's men take on Spain needing a draw to reach the semi-finals, following a dramatic fightback in their last match from three down to draw with Australia.
