Jessica Ennis has another treasured possession from the World Championships to go along with her heptathlon gold medal - a picture with Usain Bolt.

Ennis secured victory in the heptathlon on Sunday night just minutes before Bolt and the rest of the field were due to contest the 100 metres final in the Olympic Stadium.

In fact the heptathletes' lap of honour was halted around the top bend by officials in order to let the final get under way.

That meant Ennis had the perfect view as Bolt blasted out of the blocks on his way to a stunning new world record of 9.58 seconds, and the 23-year-old from Sheffield met up with the Jamaican as they attended their respective press conferences afterwards.

"It was great to be right there at the 100m start line to watch such a brilliant race and then finish our lap of honour as well," Ennis said. "That was an added bonus. We were directly looking at the start line, we couldn't have been in a better place.

"It was unbelievable, everyone knew he was going to do something spectacular, like he always does, and it was even more satisfying to be there, right alongside it watching it.

"And I got a photo with him afterwards. I saw him after his press conference and we congratulated each other and we had a picture taken, so that was nice.

"He's an amazing athlete, an inspiration and is great for our sport."

Ennis had planned to also compete in the individual 110m hurdles on Tuesday night, but decided discretion was the better part of valour after her exploits over the weekend.

And she will also decide over the next few days whether to contest a heptathlon in Talance, France next month, where she could break the British record of 6,831 points set by Denise Lewis at the same venue in 2000.

"Right now my legs are so heavy I can't imagine doing another heptathlon in a few weeks but we will see," Ennis added. "I've decided not to do the hurdles because I'm really tired.

"It was a really late finish and everything is aching so I think the wise thing to do is to pull out and just enjoy the moment and relax a little bit.

"I got about three hours sleep on Sunday night. I feel really tired but just can't stop smiling. I'm just in shock really. It's not really sunk in.

"Last year was so horrible but I knew that as soon as my injury started to heal I knew it was not going to be career threatening, I had to focus 100 per cent on the world championships and my realistic aim was to come here and win a medal. I didn't think it would be a gold medal.

"I didn't for one minute imagine I would lead from the start to the finish or be ahead by that many points. Everything just went so well and came off. It's been such a nice year. Everything has gone really, really well."
