Mo Farah's third golden double is still right on track
Mo Farah recovered from a last-lap trip to keep his tilt at another long-distance double alive on a day which saw Dina Asher-Smith and Zharnel Hughes underline their World Championship medal potential.
Three days on from taking the 10,000 metres crown, the 32-year-old began his bid to retain the world 5,000m title at the Bird's Nest in Beijing.
Like Sunday, though, there was a heart-in-mouth moment as Farah almost hit the deck after a tangle of legs around the final bend, only to regain his balance and finish in 13 minutes 19.44 seconds.
It was enough to see the Briton qualify for Saturday's final behind Ethiopia's Yomif Kejelcha, keeping his hopes alive of a record-breaking third successive long-distance double at major global championships.
"I nearly went down - again," Farah said.
"I hope it doesn't become third time bad luck."
Teenager Dina Asher-Smith spearheads the women's charge and laid down the gauntlet, setting a new 200m personal best in the heats.
Danny Talbot missed out on the final of the men's 200m despite clocking a 20.27s PB in yesterday's semi, but Hughes will represent Britain against the world's best, including Usain Bolt and Justin Gatlin, after winning his race in 20.14.
Meanwhile, World champion Julius Yego insisted Kenyan athletes could still be trusted to win clean after he landed javelin gold on the day that two of his team-mates became the first competitors to fail drugs tests at the World Championships in Beijing.
Joyce Zakary and Koki Manunga accepted provisional suspensions after returning positive tests before the start of the championships, the International Association of Athletics Federations announced.
Yego, talking about the news that two of his compatriots had failed tests, said: "I can't dwell on that, it's a shame.
"I always believe you can win clean. In sport you win clean," he added.
