I once ran partnered the winner of Leeds and other marathons in the HH and he dropped out at Mankinholes. I had been pushing all the way wondering when he would start running well as he could destroy me then but that was one of the first signs he had that he was going to need heart bypass surgery within the next few months. Still finished sub 5 but did not count as were were no longer a 2 man time. In fact all 3 times I raced it I was sub 5 which I think was the limit for the Elite category. Only time I have been elite in my life. Happy days.
