Many of us cheered as Captain Tom Moore - a 99-year-old retired soldier - completed his final lap of his garden.
Captain Tom looped around his garden 100 times using his walking frame. His original plan was to raise £1,000 for the NHS.
His actions inspired thousands to donate and he has now raised over £27 million for the NHS and released a charity single!
Although his 100th birthday isn't for another week, Captain Tom has already got a lot more than 25,000 cards to celebrate his special day sent in members of the public.
There were so many birthday cards Royal Mail had to programme a special sorting machine to process all the post going to Captain Tom's house.
Royal Mail will even be celebrating Captain Tom's birthday in their own special way, by using a special postmark wishing him a happy 100th birthday. It will appear on all stamped mail across the UK starting next week.
Many of you have spoken about what an inspiration he is to you.

Six-year-old Frank has a condition called spina bifida - which means he needs to walk using a frame like Captain Tom.
After seeing what Captain Tom was able to achieve, Frank was inspired to walk 10 metres a day to raise money for the NHS - an incredible thing for Frank to do!
Frank's efforts have seen him beat his original aim of raising £99.
Now he has been able to raise an incredible £90,000 in just a few days!
