On day one of the athletics at the Olympic Stadium in Rio, the women's heptathlon is among the highlights where two Brits will tussle for gold. Jessica Ennis-Hill reclaimed her world title in Beijing last year in her first major competition since giving birth, and is the huge favourite to retain her Olympic title she won so memorably in London. Her main competition could come from Liverpool's Katarina Johnson-Thompson, the European Indoor pentathlon champion, whose rapid improvement makes her a strong contender for the podium. Overseas competition comes from Canada's Brianne Theisen-Eaton - wife to decathlete Ashton Eaton - who took silver behind Ennis-Hill in China last year. The bronze medallist Laura Ikauniece of Latvia is also among the contenders.

Helen Glover and Heather Stanning meanwhile will attempt to convert their five-year unbeaten record in the women's pair and claim Great Britain's first rowing gold of the Games. The duo won the first gold at London 2012 and are expected to retain their title at the Lagoa Stadium.
