Mo Farah Versus Usain Bolt. Who wins in your eyes?

Usain Bolt became the first man to defend an Olympic 100m and 200m sprint double.  With legendary status already seemingly secured as well as global staredom, Bolt overcame the pressure and delivered despite his setback last year in Daegu.

Meanwhile, Mo Farah had been trying for years to reach the world class standard in distance running, constantly falling short and unable to challenge the established Africans.  Finally he broke through in 2011 becoming a world champion, so the pressure was on in London 2012.  Like a true star he delivered and tonight became only the seventh man to execute such a superhuman double.  The stadium erupted as well as the nation following this great achievement.
