Z5K training W1 calf cramps, overdoing it?
Hi all, I am now 53 yrs old and 103Kg, I decided to walk,cycle and take on step aerobics to get fitter and have been seeing some success over the last month. I found ZK5 and feel the training is very motivating so I began last week having not run or jogged for 10 years plus or more :embarassed: I had been doing 18Km cycle…
