When you are 2,900m above sea level, have climbed 8 summits and have a further 15km to run, you must be “positive” or, to put it in a proper way, you must be extremely psychologically resilient.

Once you reach that point, you no longer depend on your legs, it is your mind and your determination that will take you to the finishing line.
