Millwall fan Catherine Robbins and her son Leon are 'running up and climbing high' the full 35 floors of Broadgate Tower in London to raise funds for Action Duchenne (Muscular Dystrophy).
The duo are undertaking the challenge in support of a family friend, three-year-old Dexter, who was diagnosed with Duchenne Muscular Dystrophy in 2018.
Leon is only nine, but as he has impressed the race organiser so much with his training, he has been given permission to compete in the adult event - that's three climbs of the tower - 105 floors, 2,631 steps in total. Lucky for Catherine, she gets to accompany him!
Catherine and Leon are asking for the support and donations of Millwall fans - and you can find out more about their challenge and donate by clicking here.
