Prince Harry challenges Usain Bolt to a re-run in birthday message

Updated: 

Not only did Prince Harry send a personal birthday message to Usain Bolt, he also went and asked him if he was ready for a re-run.

The prince tweeted from Kensington Palace's official Twitter account @KensingtonRoyal congratulating the Olympic champion. As you've probably heard, Bolt secured his historic "triple triple" in Rio - that's winning three gold medals in three successive Games.

And Harry teased the sports star by posting a photo of himself racing ahead of Bolt in 2012. ICYMI, during a visit to Kingston, Jamaica, the prince jumped the starting gun to beat the world's fastest man.

Harry wrote: "Congratulations @usainbolt - now you're officially the greatest you might be ready for a re-run!." Finishing it with a winking emoji, he added: "Happy 30th" and signed off the message "H".

The Jamaican sprinter turned 30 on Sunday after a triumphant turn in Rio, winning the 100, 200 and 4×100 metres titles.

Harry and Bolt hit it off four years ago during the prince's Diamond Jubilee tour of Jamaica.

Bolt stepped up to the challenge, tweeting back to Harry that the re-match was on.

Awwww, that's a great bromance right there.
