Now for the women’s 100m heats. The first sees the US’s Melissa Jefferson-Wooden win in a time of 10.99. That looked easy for the Olympic bronze medallist. Dina Asher-Smith goes in the second heat. Three to go through, and Asher-Smith makes it, second behind Tina Clayton, the young Jamaican.

The women’s long jump was going ahead while those steeplechases were taking place. Tara Davis-Woodhall, the Olympic champion, makes it with her first jump, of 6.88m. It’s 6.75 to qualify, and the others are having their struggles.
