I had struggled at the 1980 Olympics in Moscow. A year later I was hit with an injury and I was out for two years. By Los Angeles I was probably only 90 per cent fit.I needed to make my first throw big. I wanted to go for a killer one. First round, first throw. Over.
There were a lot of elements I had to get right. There was the issue of my planting foot. It was that leg I had injured. I had lost an inch and a half off my calf. Then I had to ensure the delivery of the point of the javelin was perfect. And I then had to gather up as much speed as possible – I had lost a bit because of the injury.
But most of all it was a mental thing: the fear factor... and Fatima Whitbread. Fatima was my fiercest rival. We had been battling against each other non-stop. But it wasn't just her. Also in the field was the world record holder, Finland's Tiina Lillak. I couldn't think about them. I needed to be locked into my own world.
And then it came to it. I remember the moment vividly. It was a nervous throw, an anxious throw. From the moment I held the javelin in the draw position and then with the speed of my arm, I knew it was big. I could feel it in my chest. I knew I had given it everything. I knew it was perfect. But I didn't know it was going to be an Olympic record.
If I hadn't have nailed that first throw, I would have had to fight to the bitter end. But it was still tough to watch the remaining five rounds. I remember Tiina's last throw. I remember thinking: "Damn, that's good." And then it came down 56 centimetres short. I just couldn't believe it.
I debated for a long time whether to take my last throw or not. I knew I had won. It was basically a glory throw and I took it. It came up short, but it didn't matter. I was the Olympic champion. Fatima gave me a big hug after that. She knew I'd won. And she was professional enough about it.
Here it was, the biggest stage, the greatest show on Earth and I had won, and not Fatima, and not Tiina. I felt great, I felt fantastic. I remember there were loads of British fans behind the barrier. They were shouting my name. The feeling then was indescribable. And I sunk to my knees.
Once you walk up to the podium everything comes to you. The emotion, the fear. It's a feeling of marvel – and all of this is for you and you alone. It doesn't matter what happens to you in your life after that.
