Fiery Farah a cut above again

Mo Farah launched the World Athletics Championships in scintillating fashion on Friday with another consummate 10,000 metres triumph.

With 55,000 of his home fans roaring their support at the London Stadium, the 34-year-old Briton sprinted away with his 10th consecutive gold medal in a global track final, a dazzling sequence that ranks among the greatest feats in sport.

Farah survived being clipped twice from behind in the final lap, nearly tripping over and being forced to take a step off the track, and he ended with cuts and bruises to his "bad legs" that needed treatment. Yet still he was able to unleash one more trademark burst down the home straight to speed away from Uganda's Joshua Cheptegei and Kenya's Paul Tanui.

The Briton clocked 26 minutes 49.51 seconds, the world's fastest time in 2017, in what proved perhaps the hardest-earned of all his magnificent triumphs as he protected his six-year unbeaten streak in major championships.

Silver medallist Cheptegei, just 20, clocked a lifetime best 26:49.94, chasing Farah all the way to the line, and Tanui 26:50.60.

It was the perfect way for him to begin his final championship as a track runner before he turns his attentions to the roads as a marathon man.

"What a way to end my career in London. It's special," Farah said, after hugging his children on the track.

"It was one of the toughest races of my life. With one lap to go I nearly get tripped, twice, that was hard. But I just had to be mentally stronger and think I didn't work this hard for nothing."

After an epic test in which the powerful Kenyan and Ugandan athletes combined with mid-race bursts to test Farah's resolve more fiercely than ever before, the Briton had to show remarkable composure on the final lap.

It was the fastest he had run in any of his five global 10,000M victories by more than 11 seconds.

Still, though, he has only done half the job with the 5,000 metres to come next week and the prospect of completing a fifth straight 5,000/10,000 distance double in global championships. Whether the battering he took will affect his hopes remains to be seen, as he was scheduled to see his doctor before deciding on his participation in the 5000.

"I've got such long strides that I got caught and at that point I was just trying to stand up and think 'I can't go down, I can't go down'," he said.

After he crossed the line, he swore that the noise in the stadium matched the incredible din of his 2012 tours de force when he won the 10,000M and 5,000M here.
