Captain Moore raised almost 40 million pounds for British National Health Service charities by completing 100 laps of his garden last April. He was knighted for his amazing fundraising efforts and passed away earlier this year at the age of 100.

To mark his 101st birthday, which is tomorrow, the Captain Tom Foundation has invited people to take on a challenge centred around the number 100 – and Williams will be aiming to complete 100 pitstops in Portimão this weekend.
