Today’s highlights at the Olympics: Tuesday, August 7

These are some of the events to look out for today at London 2012.

Britain only need one more gold to equal their tally from Beijing and it could well come today.

We could win two medals as brothers Alistair and Jonny Brownlee go in the triathlon at 11.30am.

The pair have dominated the sport in recent years and the boost of a home crowd should help them through too.

More good medal prospects come in the final day of action in the velodrome as Sir Chris Hoy goes for gold number six in the keirin with the heats at 10am and the final at 5.57pm.

Victoria Pendleton has her final chance for gold before retirement in the sprint with the semi-finals at 4pm before the gold medal race at 5.26pm.

And Laura Trott sits in joint first overnight in the omnium, halfway through the multi-event contest with three more events today.

Following Team GB’s best show-jumping performance in 60 years, taking gold yesterday, their dressage counterparts could do the same. They hold the lead going into the final round.

On the track, Usain Bolt begins the defence of his 200m title with the heats at 11.50am while GB’s triple jumper Phillips Idowu will also look to qualify for the final at 10.45am.

Other Brits in action include Tiffany Porter in the 100m hurdles semis (7.15pm), Robbie Grabarz in the high jump (7pm) and Lawrence Okoye in the discus.
