Almost lost in the type surrounding Bolt in Beijing, the Ethiopian's golden double in the 5,000m and 10,000m was arguably an even greater achievement.

The world record holder at both 5,000 and 10,000, he can justifiably lay claim to being one of the greatest distance runners of all time and will be the man to beat in London if he can arrive fully fit after two years of injury problems.

After pulling up in the 10,000m at the 2011 world championships with a ruptured muscle, his aura of invincibility was under threat and he must decide whether his body can cope with the Olympic double again.
