Jessica Ennis says she will not run in the 100m hurdles following her Olympic triumph in the heptathlon.
The 26-year-old from Sheffield considered competing in the event, which starts on Monday, after running a personal best time of 12.54 seconds in the first discipline of the heptathlon.
"I did think about it, especially when I ran a personal best," she said.
"But for me it was just about the heptathlon. I'm more than happy with that and I just need to rest now."
