Sebastian Coe
The LOCOG chairman is in abullish mood as he rounds the final bend of preparations for the "greatest show on earth". He's under no illusions that this push for the line is the toughest of his storied career. The next 210 days until the Games open are about ironing out operational issues and the finer details. As the clock ticks down, Coe will also spend time traveling around the U.K. to spread the Olympic spirit. After spearheading the successful 2012 bid, meeting the expectations of a nation and the world, including the Olympic Family, will owe a great deal to his leadership.

Ensuring IOC members, athletes, officials and VIPs are not hampered by such issues is part of his remit.
Hugh Robertson
The man who succeeded Tessa Jowell as Olympics minister has carried on her excellent work. But his job is about to get harder.

Colin Moynihan
The outspoken chairman of the British Olympic Association has a legal battle with the World Anti-Doping Agency at the Court of Arbitration for Sport on his mind while trying to inspire confidence in the 550 athletes who will represent Team Great Britain at the Games.

Roger Mosey
The BBC's director of London 2012, overseeing all the Olympic coverage of the U.K. rightsholding broadcaster , is responsible for bringing the story of the London Games to audiences at home. It's the biggest BBC project since Queen Elizabeth II's coronation in 1952. His reputation rests on the BBC's smooth delivery of all the dramatic sporting highs and lows and Games controversies across all media platforms.
Paul Deighton
The LOCOG chief executive's double act with chairman Coe in preparations for the Games - and in deflecting criticism - has worked well. Now the heat is on. Deighton must navigate his way through a mountain of operational issues in the coming months - delivery of the volunteer workforce among them - to ensure the stage is set for a spectacular Games.
Craig Reedie
Since joining the IOC Executive Board in 2009, the amiable Scotsman has been an important link between LOCOG's top brass and president Jacques Rogge, while doing everything he can to bolster London 2012's profile at international meetings. Having played a significant role on the bid team, the LOCOG Board member will take great pleasure in the accomplishment of a successful Games.

Usain Bolt
The Jamaican, star of the Beijing 2008 Olympics, could provide the iconic sporting moment again in the 100m on Aug. 5. Keen to shake off the ignominy of his false start at the Daegu world champs, Bolt faces competition from countrymen Yohan Blake and Asafa Powell for the sprint title.
