The Captain Tom 100 Challenge Captain Tom 100 – Everyone's invited All you need to do is dream up a challenge based around the number 100, and do it between Friday 30 April and Monday 3 May. You could walk 100 laps of your garden just like Captain Tom, swim 100 lengths or sing for 100 minutes. There are no rules (apart from Government guidelines on the roadmap out of lockdown) and it's open to everyone. Do it your way and have fun! You could pick one of the ideas below, or come up with your own!
