TICKHILL athlete John Mayock became the first Briton to run the 2000 metres indoors in less than five minutes when he beat his own record in France on Sunday.

Mayock clocked 4.57.09 in finishing second to Olympic 1500m champion Kenya's Noah Ngeny, who claimed victory in 4.56.40 at the Gaz de France Pas de Calais meeting in Lieven, France on Sunday.

He was almost 20 metres behind Ngeny at the start of the final 200-metre circuit but he produced a superb finish to end just five metres behind Ngeny, whose time was the sixth best in history.

After the run, which beats his own British record of 5.02.53 by more than five seconds, Mayock put it down to high-altitude training with Hicham El Guerrouj.

"Training with Hicham was brilliant," he said. "Since my return, I've set new PBs 1500 metres and the one mile and now at 2000 metres, all in the space of ten days.

"I know I am stronger than I have ever been and I can thank Hicham for this. I am raring to go for next month's world championships in Lisbon where I will be running the 3000 metres."
