In boxing, it's one fight, so it's easier to build up rivalries, but everyone's got huge respect for each other.

It's a huge step up from the European Indoor Championships to being world outdoor gold medallist.

At primary school, it was always me and this other girl, Lauren, who would fight over who was the fastest every year. I was quicker, but for some reason, she always got the glory leg in the relay team. That used to annoy me.

When you see all the medals won by Team GB, you can just see how much it means to each and every athlete, so it just feel like it's a little bit of a missed opportunity - but I'm only 23. I have just got to get on now and keep going.

No one put pressure on me to go to the Olympics; once I'd got the qualifying mark, I just couldn't say no.

The heptathlon is made up of seven events, and people have strengths and weaknesses.
