My training app sends me a daily notification saying it's disappointed with me.

I've been battling colds, flus and stomach bugs since January.

And my knee has started making a weird creaking noise.

But come hell or isotonic water, on the 12th of April, I will be taking on the London Landmarks Half Marathon for The Children's Society. TCS does incredible work, tirelessly working to protect society's most vulnerable young people.

In the face of poverty, county lines gangs and government cuts, they bring light to the dark and hope where there's none.

Suddenly a creaky knee doesn't seem like such a big deal. Nor does chucking in a couple of quid to help them out.

Please donate whatever you can, no matter how small, it really will make a massive difference.
