Two great athletes; two different contrasting styles. One is a showman and relishes every opportunity in front of the camera.

The other is self-effacing, humble-even shy. Yet they both produce great results, one that leaves the world dazzled, a rare privilege for those that watched the London 2012 Olympic Games. One is a Kenyan, the other is a Jamaican.

They live thousands of miles apart, yet they capture what the essence of sport should be. David Rudisha and Usain Bolt are no doubt the greatest athletes of their generation, one that millions of viewers will live to remember.

I must admit that I had prepared a very stinging article about the performance of the Kenyan athletes in London. However, after the magical performance of David Rudisha in the 800m men's final, I had to acknowledge that what just beamed on TV screens across the world was greatness. He made my Olympics; I had been disappointed for days, and even at times contemplated not watching the Olympics at all.

In short, he had made up for the dismal performance of the other Kenyan athletes in London. While Rudisha concentrated on training for the Olympics, and even missed one or two diamond leagues, the other Kenyan athletes were tired and exhausted from taking part in so many diamond leagues and races.

It is true that the international media gave Usain Bolt more airtime and space, but Rudisha's performance was just as phenomenal. Both men have immense respect for each other, and that moment when Bolt ignored a BBC reporter to pay homage to Kenya's national anthem just did it for me. Rudisha's running was smooth and languid-even effortless, and there is a big chance that he might break his own record again for the third time.

With his poise and eloquence, in both Kiswahili and English, fortune will follow. Endorsements (advertisements), from major companies will swell his bank account but I hope he has been prepared for the success that will soon follow him.

Is he prepared for the increased media scrutiny, attention from more women, how to handle millions, globe trotting and international travel? Has his coach and manager prepared him for life outside the track as well?
