Long jumping sounds simple - you run fast and jump well. But it is about getting all the technical bits right.

It was not about the guy who could jump the furthest; it was about the guy who could jump the furthest on that particular day in the worst conditions of any Olympic long jump final.

It's perseverance that's the key. It's persevering for long enough to achieve your potential.

I still do cardiovascular exercises, aerobic exercises, and then strength training, as it's important to keep your muscle strength, as every decade you lose about 10% of this.

It's about somebody initially knowing more about it than you do but eventually you learn a lot about it yourself and practise the skills and techniques that you've been taught.

I've been involved in sport right through my life.
