I did change my shoes and socks once..not really sure why but I thought it was the done thing! Funny enough my pre race anxiety was very much focussed on blisters..lord knows why as I can't remember the last time I had one..Berlin 2008 ish I think?
I always wear Hilly twinskins and have since time began and I use Xenofit on my feet..which contains deer musk sorry lovely deers!
When I feel like being a bit girly I do give my feet a bit of a pamper, oh and I always have my toe nails painted even though they have a tendancy to drop off!
I think we expect a lot of ourselves and probably too much at times. A week on from my aborted 100 (at 80 miles) my legs feel ok except for a niggle behind my knee but when I had to do a bit of running on a coaching course yesterday..I just felt flat..in fact I felt flat of mind too...but that is another ball game to play!
