Pippa Middleton has written a piece for Hello! magazine about running a Marathon in Kenya.
"I decided that a marathon was a 'life box' that needed ticking and this year was my time – despite it being one of the toughest in the world, with temperatures rising to more than 30ºC, at an altitude of 5,550ft and with the possibility of bumping into lions or rhinos," she wrote.
She eventually finished the race in three hours, 56 minutes – placing her 30th overall out of the 200 competitors.
"I was exhausted. My eyes welled up with tears," she wrote. "Could I really manage this? I turned right and thought of the schoolchildren, the rhinos, elephants and lions, the incredible Tusk projects – the reason I was doing this. It was tough – tougher than anything I’d been faced with before and required every inch of my energy, stamina and stubbornness."
