Farah’s farewell to London

Sir Mo Farah takes a picture of himself in the London Stadium, the scene of his Olympic triumph five years ago, and where he will run his penultimate track race tonight in the 10,000 metres at the World Athletics Championships. Britain’s most decorated distance runner intends to concentrate on the marathon after the championships

Brits to watch

Only one gold medal will be decided on the opening day of competition and it is likely to be Britain that claims it with Mo Farah (below) the firm favourite to retain his 10,000m title. The four-time Olympic champion is unbeaten at major championships for six years and has continued to repel anything the east Africans have thrown at him. Chijindu Ujah will lead Britain’s 100m sprinters as they begin their campaign in the heats, Laura Muir should have no problem advancing through the first round of the 1500m, while Holly Bradshaw goes in pole vault qualifying.

Foreign star

Luvo Manyonga. He may not have triumphed in Rio last summer, when he claimed Olympic long jump silver behind American Jeff Henderson, but the South African has progressed markedly this season, jumping beyond 8.60m – a distance not reached anywhere since 2009 – four times. He will expect to breeze through qualifying before launching an assault on the world title tomorrow.

Don’t-miss event

Men’s 10,000m. The only final to be contested on the opening night of competition will see Mo Farah attempt to win the world title for the third time. As ever, his main threats will come from the east Africans. Kenya’s team features Geoffrey Kamworor, who claimed silver behind Farah at the last World Championships, while Ethiopia have Abadi Hadis and Jemal Yimer – the two fastest men this year.
