‘Because of the extreme temperatures and the weight I’ll be carrying, it will be an immense challenge but I’ve put in lots of miles already and in terms of physical and mental fitness, I’d say I’m now in peak condition,’ she said. ‘Obviously my main aim is to complete the course and cross the finish line.’
