Mo Farah won Great Britain’s first gold of the championships as he took first place in the 10,000m. The 32-year-old Olympian beat Kenyan runners Geoffrey Kipsang Kamworor and Paul Tanui with a time of 27:01.13 – no mean feat in 25°C heat and 60% humidity.
Usain Bolt took gold for Jamaica in the men’s 100m, beating the USA’s Justin Gatlin by just 0.01 seconds. Bolt remains unbeaten in the 100m and 200m since the 2008 Beijing Olympic games, minus a single disqualification for a false start.
Jessica Ennis-Hill won the heptathlon gold in her return to competing after having her son Reggie last summer. Fellow Briton Katarina Johnson-Thompson didn’t perform as strongly, failing to place in the long jump and subsequently finishing 28th in the 800m.
Hurdler Jack Green, who returned to competing this year after taking a break to recover from depression, has had to pull out due to severe sciatica. Green was due to compete in the 400m hurdles and 4x400m relay.
