One of the extraordinary things about Gordon Pirie was that although he liked to run fast he also ran long - he set a Guinness World Record for "Greatest Mileage" of 347,600km over 40 years - approx 580 hours per year or 167km per week. How would he compare to modern Attackpointers? Well, a quick search can't really find anyone doing a similar amount (best single years for the APers):
