This year I am taking on a really exciting mini-triathlon challenge with my school friends, and thousands of others across the country. I’ll be swimming, cycling and running in a relay with my team to raise money for Restless Development and my school’s chosen charity.

This challenge is extra special because my identical twin sister, Matilda, was meant to be taking part too, but she has sadly broken her ankle and can’t join in. So I’m hoping to raise double the money and do it for both of us.

Together, we can make a huge impact on the world — and every donation, big or small, will mean so much.
