Sebastian Wood, the British ambassador to China, launches a special racing event in Beijing marking the 100 days to go until the London 2012 Olympic Games at Beijing Sport University on Wednesday.

Wood, a track and field fan himself, expressed his enthusiasm for the Games by supporting the 100m race "from Beijing to London" run by Olympic athletes and 100 students from the university.

The Olympic-themed relay race was organized to symbolize the journey through all 30 Olympic Games from the 1896 Athens Games, the first Olympic Games in the modern era, to the present one.

As British embassies across the globe marked the 100-day milestone, the British ambassador also visited the Chinese rhythmic gymnastics team training at the university, asking them about their final preparations and watching their spectacular displays.

He introduced students and the media to a screening of "Game Changer", a short film about the UK's preparations for the Games, which showed that the whole of Britain is ready and prepared to welcome the world to what promises to be the greatest show on earth.

The Olympic Park will be glittering at the center of the events, and celebrations demonstrating British engineering, design, creativity and ingenuity, the video showed.

Speaking of the partnership between the UK and China, Wood hailed the Beijing organizing committee's efforts to put athletes at the center, part of the lessons that Britain learned from the Beijing 2008 Games.

He expressed his excitement about being in London for the opening ceremony and passed on messages from UK Prime Minister David Cameron and Chairman of the London Organizing Committee Sebastian Coe.
