I am moving in to week 6 this week. Yesterday I took part in my first ever park run. I walked about 2k of it and completed it in 45 mins. I am so pleased with myself. Just a quick question on rest days I am doing a brisk 30 minute walk and so far it’s been ok although during the park run my calf muscles became very tight and I had to walk it out to stop cramp setting in. What do people think about walking between runs?
