Ethiopian Almaz Ayana destroyed the field to win the 10,000 metres at the World Championships on Saturday, finishing about 300 metres clear of her rivals.

The Olympic champion, who has not raced on the European circuit this season due to injury, began pulling away from the field after 10 laps, sweeping past back markers who were made to look sluggish in comparison.

She finished in 30:16.32 seconds, well outside the world record she set when she won in Rio last year but still an astonishing 46.37 ahead of her compatriot and former world and Olympic champion Tirunesh Dibaba who took the silver.

Kenya's Agnes Tirop claimed bronze.
