star Usain Bolt in the morning to Jessica Ennis and Mo Farah in the
evening.
Here are Saturday's events to watch out for (all times BST):
Full schedule available on BBC Sport website
- ATHLETICS (10:05-21:14): Jessica Ennis, heptathlon; Mo Farah, men's 10,000m;
Mo Farah then goes for the first of a possible two medals in the 10,000m (21:15), and the fastest women on earth line up in the 100m final (21:55). Earlier in the day, Usain Bolt and his fellow sprint stars take part in the men's 100m first round (12:30 to 13:20). South Africa's four-time Paralympic champion Oscar Pistorius will make history as the first amputee sprinter to compete at the Olympics when he goes in the men's 400m (10:35).
- TRIATHLON (08:55): Helen Jenkins
Jenkins might not have the
profile of Brownlee brothers Alistair and Jonny but the Welsh triathlete
is herself a world champion and in great form heading into Saturday's
Olympic race at Hyde Park. She will have help from team-mates Lucy Hall
and Vicky Holland. Australia's Erin Densham, Swiss Nicola Spirig and
Paula Findlay of Canada could be among the medal threats.
- ROWING (11:30): GB men's four
Britain have won the men's four at the last three Olympic Games but recent performances by Australia suggest they have the speed to match the power of Andrew Triggs Hodge, Pete Reed, Tom James and Alex Gregory - the Olympic final could be a sensational battle.
- TRACK CYCLING (16:11): GB women's team pursuit
- SWIMMING (20:27): Michael Phelps, men's 4x100m medley
- TENNIS (14:00): Serena Williams, women's singles
- FOOTBALL (19:45-21:30): GB men
