Probably one of the most nervous times I ever had in my career was building up to the 2006 World Championships in Assen.

Even though I was Paralympic champion, I had never won an individual world championship medal and I knew this would probably be my last chance to win one and say I was a good enough athlete to medal at every major event.

I can remember walking my dog one day and the thought struck me that in four weeks' time it would be my final. From that moment on, the nerves really got to me and I felt so ill that I could have quit at any time.

But I went out there and won to achieve a career dream. I call it the icing on my career cake.

The only downside was that at all the other major championships where I missed out, the medals were ones to be proud of, but in Assen the medal was one of the most abysmal.

I've given out better medals at school sports days. It's funny that although it's the medal I'm least proud of, the title means so much to me.
