Highlights in detail

On the evening of 'Super Saturday' - 4 August, 2012 - Mo Farah, Greg Rutherford and Jessica Ennis-Hill all won gold in a defining, deafening hour of Olympic success for the host nation. If that's going to happen again in Rio, tonight is the night - the long jump starts at 00:53 on Sunday, Farah's 10,000m follows at 01:27 and the heptathlon's 800m finale is at 02:50. Ennis-Hill leads the standings after day one and one of her main challenges should come from British team-mate Katarina Johnson-Thompson, who is fourth after day one.

And that's not all on the track. You may have heard a lot about trebles when it comes to Usain Bolt, but there's one person who could beat him to three straight Olympic 100m titles: Jamaican team-mate Shelly-Ann Fraser-Pryce. The 29-year-old Beijing and London champion has struggled with a toe injury but is still expected to be on the start line for the final (02:37 Sunday). The field should be full of gold medal contenders: Dutch sensation Dafne Schippers, another Jamaican in Elaine Thompson and Americans Tori Bowie and English Gardner.

Britain's women are in the spotlight at the velodrome on Saturday (morning session from 14:00 BST, evening session from 20:00). The women's team pursuit was a nailed-on British gold medal at London 2012 and set a world record in their qualifying ride in Rio. They will now meet Canada, runners-up at the 2015 World Championships, for a place in the gold-medal race. In the same session, 2013 world champion Becky James will hope for a medal in the keirin - the race where a motorbike acts as pacesetter before pulling away for the dramatic final laps.
