After lots of reading and having aching calf muscles on the last 2 runs, we went for Gait Analyisis today at the only place in Cumbria that does it, Chivers Sport in Carlisle (40 miles away). Wow! was I impressed. Even more so with my daughter in law that also came for hers too. After an hour or so she was even walking in more comfort than she has done for ages. My new trainers feel soooo much better than my old trainers, or rather "walking shoes" as he called them lol. So 2 Analysis sessions and 2 pairs of PROPER running shoes and £190 lighter. I feel it was money well spent. First run in them in the morning, I have done (attempted) 2 sessions of W4 but I am going start it again , hopefully smilling too.
