About The Author

Editor-In-Chief at BOXROX. I come from a background of rugby and weightlifting. Growing up in the English Lake District, I spent a great deal of time swimming in its stunning lakes and rivers. In 2015 my brothers and I became the first people to swim the 145km length of the River Eden, from source to mouth, in 9 days. We also swam the Corryvreckan whirlpool, the third largest in the world, and Crossfit is a huge part of my training for these events.
