I did W8R3 yesterday in the country at 800-900m altitude and the blasted hills got me - I just had to walk for four bits of about 30-60 seconds - grr.
Particularly annoying as I did the 28 mins twice last week on flat ground. Anyone else running high up? Is it true that it makes a difference? Or am I just being weedy about the hills?
Doe this mean I can't start W9 next week? Mind you, I'll be in hill country all week, so I doubt I'll do it!
