These are the Brits you should be watching on Day 2 of the Olympics
These are the Britons to spur on on the second day of the Olympic Games:
The Scot expects to be in action for the first time since winning Wimbledon for a second time last month, as he gets the defence of his Olympic men's singles title under way with a first-round encounter against Serbia's Viktor Troicki on Sunday.
He could also play alongside brother Jamie against Brazilian pair Thomaz Bellucci and Andre Sa in the men's doubles.
Armitstead claimed Britain's first medal at London 2012 by winning silver and she will hope to put a turbulent week behind her by going one better in Rio in the women's road race, which gets under way at 4:15pm BST.
If he successfully negotiates the heats and semi-finals of the 100 metres breaststroke on Saturday, Peaty will be eyeing top honours in the final. Set your alarms for around 2:45am.
Helen Glover and Heather Stanning
The reigning Olympic, world and European champions are in the rowing heats of the women's coxless pair at roughly 2:10pm.
Colin Oates and Richard Kruse
London judoka Oates competes in the -66kg category from approximately 2pm while fencer Kruse is also in action around the same time.
