Thanks for posting this Chris and I was sorry to hear of Harry's passing. Harry was my form-master and taught me physics at Ullswater School in Penrith in the very early 1970s. My fellow pupils and I were unaware of Harry's athletic skills and thought it a bit weird that he spent so much time in scruffy running kit. When I started taking an interest in fell running many decades later, I found out that Harry had been at the top of the fell running tree at that time.
I did eventually get to run the same race with him at Arnison Crag in Aug 1999 when he would have been a V60.
