Walk training commences

I'm off for a 102 Mile walk along the Macmillan Way West from Barnstaple to Castle Carey in September in 6 days. It takes a little working up to as the first day is a Yomp practically all the way across Exmoor so some practice is required. Yesterday was my first 8 mile training walk with a pub and a curry dinner in the middle. At least my pack is lighter this year as i have left all the cooking equipment behind, water and cold rations this year with hot pub food to look forward to. I'll continue to post my progress here, shifting 1 stone before the walk would reduce my load considerably. Any comments on how to toughen your feet would be most welcome!
