Prince Harry challenges Usain Bolt to another race

Prince Harry has jokingly challenged Usain Bolt to a re-run after the Olympic sprinter let the 31-year-old royal win a race back in 2012.

The 31-year-old royal wished the Jamaican sprinter - who turned 30 on Sunday - a happy birthday and also wished him well in the 2016 Rio Olympics.

A message on behalf of Harry posted on Kensington Palace's Twitter, read: "It has been an incredible few days of competition in #Rio2016 as we head into the final events ... We were also watching the sprinting closely last week and have a special message for one of the competitors on his birthday ... Congratulations @usainbolt - now you're officially the greatest you might be ready for a re-run! Happy 30th - H (sic)"

Meanwhile, Harry is set to celebrate with Usain after his seventh Olympic win.

Harry has been tied into partying with the sportsman after he gained his seventh gold medal during the men's 100-metre sprint at a time of 9.81 seconds.

The champion has revealed he plans to enjoy a night out on the town after the sporting extravaganza where he will teach the flame-haired party-goer some of his best dance moves.

He said: "I'll party with Harry and teach him the running man. But only after Rio!"

Harry and Usain first met each other when Harry visited the athlete's hometown in 2012, which saw the two perfect Usain's signature lightning bolt stance and strike the pose together.

Meanwhile, Usain plans to earn himself and his country two more medals and reach the goal of owning 10 gold trophies before he can declare himself as an "immortal" being.

He explained: "Somebody said I can become immortal. Two more medals to go and I can sign off. Immortal.

"Somebody said if I win these three gold medals I would be immortal and I kind of liked it. So I'm going to run with that one."

Regardless of his goals, Usain has admitted he is "proud" and "happy" with his achievements and success in the games so far.

He added: "I'm happy and I'm proud of myself."
