I have completed week 2 run 3 today. The humidity was a killer, I normally run about 6am and the air is generally quite fresh - didn't like the heat at all - its put me right off the beetroot I had planned for lunch!!
My feet were certainly uncomfortable but interestingly feel better now I am home and rested and the one with the temporary support is much improved so fingers crossed that I have found the answer. I stayed on the soft grass in the park too instead of heading for the farm tracks, definitely softer underfoot and a more level surface too so less foot twisting. Also meant I didn't have to cross the lake that has formed in the corner. Our village is becoming very close to being cut off, both roads to the village are currently flooded and we are expecting more storms later
Given the problems I am having with my feet I don't feel ready for week 3 yet, I need to be more confident so am going to continue with week 2 until I am happy. Think I am going for c25k in 18 weeks not 9!!
