Today’s highlights at the Olympics: Friday, August 3

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

The Olympic Stadium comes back to life on Friday as track and field events at London 2012 begin.

Jessica Ennis is in action early, as she begins her heptathlon campaign, starting at 10.05am in the 100m hurdles, followed by the high jump (11.15am), shot put (7pm) and the 200m heats from 8.45pm.

Ennis, a leading British hope for athletics gold, concludes her event on Saturday.

In the pool, Rebecca Adlington goes in the women’s 800m freestyle tonight.

This afternoon, Victoria Pendleton will feature in the women’s keirin while the GB men will battle it out in the team pursuit.

At around 3pm, Andy Murray plays Novak Djokovic in the men’s tennis singles.

Murray is certain to play for a medal after reaching the semi-finals but he faces a major test if he is to battle for the gold, as he is facing the recently deposed world number one.

Elsewhere, GB women’s football team play Canada at 7.45pm.
