Thank you all for your help. x
Anglaise and Custardcreams* The walk is all around central London so it will be nearly all road walking and I'd say, not too hilly. (I hope!)
For my treadmill I usually wear a pair of Reebok trainers, very lightweight and comfy. I've never had problems with them before but I've never spent 90 minutes on the treadmill before and I don't think the sole is as padded as it could be. I know I will not be walking at that pace so the impact won't be as concentrated but the distance I need to cover will be the killer.
I have since got myself a few pairs of 1000 mile socks which will hopefully provide me with a bit more padding! LOL
The pain was fairly short lived, I took my trainers off and walked around with bare feet initially but my soles felt so bruised I put my Crocs on for the rest of the evening. Next morning my ankles and calves were a bit tender but nothing much.
I do have a pair of walking boots which are heavier. I tend to use those mainly on holiday walks and although I probably cover further distances in them, I haven't considered them or trained in them for the Shine Walk.
I have a Fitbit and on a day with no training I cover between 6-12K. My issue has been not being able to train for distances, especially over the school holidays as I had no respite for my daughter.
What are the numbers for on the posts please?
