Noah Lyles runs 100m in personal-best time at Diamond League London

Noah Lyles warmed up for his assault on the Olympic 100-metres title in impressive style on Saturday as the American world champion ran a personal best of 9.81 seconds in the final Diamond League meeting before the Games.

Lyles, probably the biggest name in the sport at the moment, delivered in the final race of the day in front of a sellout crowd of 60,000 in London, easily the largest on the Diamond League circuit, clipping two hundredths off his best.

Lyles has developed into the biggest personality in athletics and, having taken the 100m world title in Budapest last year to add to three, and an Olympic bronze, over the 200m, he is becoming the man to beat in the marquee event.

"That was fun," said Lyles, who was sluggish out of the blocks but supreme over the second half of the race. "I could have had a better start but the transitions were great and coming away with a PB this has been what I prayed for and what I wanted."
