You could choose to walk 100 laps of a track, run 100km, hop 100 metres, cycle 100 miles or even bake 100 small cakes as part of a new fundraising campaign in memory of Captain Tom Moore.
Launched this week, on the anniversary of the day that the late Sir Tom set out to walk around his garden, the Captain Tom 100 initiative calls for people to take on a challenge focused on the number 100.
The fund-raiser will run from Friday April 30, which would have been Sir Tom's 101st birthday, and finishes on May 3.
Cash will go to The Captain Tom Foundation.
Captain Tom Moore's legacy
On April 6, 2020, Sir Tom set out to walk 100 laps of his garden to thank the NHS heroes of the Covid-19 crisis. He went on to raise an incredible £38.9 million for the NHS Covid-19 appeal.
His simple message of hope – “Tomorrow will be a good day” – inspired millions around the world and brought comfort to many people during the pandemic.
Sir Tom passed away earlier this year, just two months short of his 101st birthday.
To honour his fund-raising achievement, the Captain Tom 100 encourages as many people as possible to walk, run, cycle, bake cakes or whatever, so long as it is focused on the number 100.
