Countdown to Rio 2016: Olympic sport this week
GB CELEBRATE EURO MEDAL HAUL
Swimming: Great Britain won seven golds at the European Championships in London to finish second in the medals table behind Hungary.
There were also victories for the men's and women's 4 x 100m medley relay, and the non-Olympic mixed medley relay.
The British team won 22 medals in all - more than any other country - seven gold, six silver and nine bronze.
ENNIS RETURNS BUT PAVEY FALTERS
Athletics: Jessica Ennis-Hill said her troublesome Achilles "feels really good" after making her first competitive appearance of the season.
The Olympic heptathlon champion threw a modest 41.69m in the javelin in Loughborough but says she is back on track after fearing a one stage last winter that she would not be able to defend her title.
Jess Andrews, in only her second track 10,000m race, won the British trials in London to qualify for the Rio Olympics, along with Scot Beth Potter.
But 42-year-old Jo Pavey, who is aiming to reach her fifth Olympics, could only manage sixth, and must now hope selectors hand her a discretionary place.
British long jump Olympic champion Greg Rutherford looked in good form in winning the Great CityGames in Manchester while Usain Bolt ran under 10 seconds for the first time this season in the Czech Republic.
South African Caster Semenya clocked the fastest 800m in the world for four years at the Diamond League meeting in Morocco.
FIJI ON COURSE FOR OLYMPIC HISTORY
Rugby Sevens: Fiji retained their World Series title after the last of the 10 rounds at Twickenham.
They only reached the quarter-finals of the London leg - which was won in thrilling fashion by Scotland - but it was enough to clinch the overall title.
South Africa finished second, with New Zealand third. England finished eighth and Scotland 10th.
Fiji's win also secures top seeding for Rio, where rugby sevens is making its debut, thus boosting the nation's hopes of a first-ever Olympic medal.
NEWS IN BRIEF
