Last year I heard a story about a man named Gary McKee, who ran a marathon every day, and raised an enormous amount for charity. If he can run a marathon every day, I thought, I can at least run 5km every day. The logistics of shift work meant that on some days, my only option really was cycling, and so just before the turn of the year I set myself the challenge to either run 5km, or cycle 25km, every day of 2023.

It's been tough going at times, but also very rewarding; I ran my first half-marathon in May, took on the UK's toughest parkrun, and very recently I cycled my furthest ever distance in one day - 107km. Now, with a little less than 100 days of my challenge to go, I'd really like to do some good by raising money for charities that are close to my heart.

I work on the Global Guidance bench at the Met Office, providing support to UK Government, the EU, and other partner agencies in relation to natural disasters and military conflicts around the world. Some of the conditions faced by children in countries affected by natural disasters and armed conflict are truly horrific, and really heart breaking to see.

UNICEF's Children's Emergency Fund helps to protect children from disasters, conflict and disease, and I'm proud to be raising money to support their vital work. Every donation will help to build a better world for every child.
