About #Challenge21 #Challenge21 has been created to celebrate the 21st's for two special Birmingham based charities Help Harry Help Others Cancer Charity and free@last. Harry Moseley who created HHHO should be celebrating his 21st birthday on the 22nd February and free@last are also celebrating their 21st anniversary throughout 2021. With the above in mind both small charities decided to do a collaborative event where all proceeds would be split between both charities. The idea is that from the 1st February 2021 to the eve of Harry's 21st birthday 21st February 2021 people will take on a challenge that will last 21 days.
