Last weekend I was shooting a convention for the Marathon De Sables.
Including workshops and a final address from Sir Ranulph Fiennes, who has led an amazing life and was billed as the greatest living explorer.
You may remember that he cut the remains of his frost-bitten fingers off with a pen knife!
If you like the idea of a challenge you can find out more about this gruelling event here:
