Some lawyers run marathons. Naz Gauri, associate at Chadbourne & Parke’s London office, has just run six. In seven days. Across the Sahara.

He was taking part in the 246km Marathon des Sables (MdS) - a seven-day ultra-marathon which includes one extra-long day when the competitors run 81km, the equivalent of a double marathon. Did we mention competitors are completely self-sufficient, carrying everything from food to anti-venom pumps in their rucksacks?

Gauri was raising money for Facing Africa, which devotes its efforts to helping child victims of NOMA, a gangrenous infection of the face.
