Venus Williams won gold in Sydney and was working hard ahead of her record-equalling fifth Olympics.

And after practice Venus was only too happy to fulfil her sisterly duties.

Fresh from her title run in Stanford, World No.13 Johanna Konta is a dark horse in the singles.

While British No.2 Heather Watson will hope to improve on her second-round showing at London 2012.

No.2 seed Angelique Kerber was all smiles ahead of her second Olympics.

Russia’s Svetlana Kuznetsova and Daria Kasatkina were also hard at work on the practice courts.

Kasatkina is one of just three teenagers in the singles draw in Rio.
