Kieran Sutherland, 15, from Wick.

I live in the far north of Scotland with my mum, my dad, and three brothers. Like millions of others around the world, I have cerebral palsy, a condition that affects different people in different ways. For me, it means I am in a wheelchair, I have poor eyesight and co-ordination, and find moving around very difficult.

David Weir CBE has been a role model and a hero of mine since I was seven.The first race I saw him in was the London Marathon.I was amazed to see what people could do in their wheelchairs. Before that, because where I live is so isolated, I had always believed that I was the only person in the world in a wheelchair.

So - as well as a sense of awe for what the athletes could do - I also had a feeling of relief that I was not alone. My health took a turn for the worse three years ago, and I was in hospital for ten weeks in a lot of pain. There were moments when I felt that I could not continue. In these moments, it was David Weir that helped me find strength.

I very clearly remember watching him win at the London Marathon and thinking: 'He has taken everything negative in his life and turned it into a positive, I need to do the same'.

Then, one day, I got a chance to meet him as part of this BBC project I’m involved with. It was a big surprise and I was so shocked when he came into the room. It left me speechless.

Some people say you should never meet your heroes because you will only be disappointed. I disagree. He was one of the nicest people I have ever met. It's a memory I will always treasure, and I'd like to thank David Weir CBE.

As I’ll be 16 in time for the independence referendum in September, I’ll get a chance to have my vote. I’ve spent this year trying to make my mind up which way I’ll vote.

At the moment all I can say for sure is that I am very, very, very, very undecided.
