We're in the midst of an environmental catastrophe and the Legion has come to help! I've picked Fauna and Flora International because our whole world needs help and this charity deals with every kind of environmental and ecological challenge!

This is why, on the 20th of June, I'll be running the length of Hadrian's Wall (70 miles) while wearing full Roman armour. I sincerely hope that you donate to this fantastic cause and that we all do our bit for our planet.
