The founders of this weekend's bike ride never even met Harry Moseley - yet they've been inspired to fundraise in his name.
Their plan is to cycle over 100 miles in 2 days, from Harry's old school in Sheldon in Birmingham - to Wembley Stadium.
Harry mum Georgie said "it's just so touching and heart-warming and Harry would never realise the impact he had on people so I just cannot believe Harry's touched everybody's hearts."
It was the hand-made bracelet that made Harry's name. He raised thousand of pounds selling them for Cancer Research.
The cyclists have already raised more than 15 thousand pound and they want the donations to keep on coming.
Harry's mother Georgie and former Blues footballer Michael Johnson will cycle for the first leg of the cycle ride today, before taking part in a 26-mile walkathon for Harry tomorrow.
