I was asked the shoe conundrum by a couple of folks in our club after we had a trot round a couple of weeks ago. For me personally it's trail shoe territory, depending what you wear and how comfy they are.
I find that my road shoes (Asics GT), although fine if it was bone dry, are basically a bit high and my feet roll around too much on rocky, divotty (is that a word?) ground.
I wear Wave Harriers, which have enough cushioning to be comfortable on hard stuff, but plenty of trail grip (unless it's wet limestone!), they've been mint on the 3 Peaks and Yorkshireman type events. So it'll be those for me.
The only problem with road shoes is that if it ain't bone dry, they can be horrible on muddy type ground, although granted there won't be loads of that......hopefully!
See you all on Sunday, looking forward to it!
