The fastest man on Earth, Usain Bolt, has celebrated his 26th birthday with a helicopter trip over the Swiss Alps.

Afterwards, the three times Gold Medallist at this year's Olympics was invited by one of his sponsors to a party near Lake Geneva in Switzerland.

"I'm looking forward to having a nice dinner with my coach, my best friend, my agent - just a few people who are close to me," said the athlete.

"I'm 26. I'm not happy about getting older, but I'm happy!"
