I'm not sure there are enough coaches in the system that can take young talent and consistently get them into the top five in the world.

World records are only borrowed.

My motivation to compete was always about improving one year to the next. At 34, I realised I'd never run any quicker, so why hang on? But I love running and still run along woodland trails and beaches every few days.

I joined the local athletics club when I was 12, that's what I did. I did it of my own volition.

There may be problems we still need to tease out, but we will leave no stone unturned in our bid to make London the host city.
