If we carry on filling up the calendar, we keep on pushing the athlete, we shorten the athletes longevity. The risk is to shorten a career that could have lasted 10 years because the athlete is burnt out.

In Cuba we use our champions to promote the sport.

I run in practically every single road race in my country, 5k, 10k just to promote the sport.

Be very strong... be very methodical in your life if you want to be a champion.

Then I received support from the Government to compete for my country, and to represent Cuba in competition.

And then you have the responsibility and the duty of being good examples to youngsters, not smoke, training hard, go to bed early, don't drink alcohol, don't take drugs, it's very important to have a policy for educating against doping.

We want to promote the great quality of athletics - and maintain it's integrity - all over the world.
