to clock up the miles It all depends on what you did when you ran before (training, eating etc.) as opposed to what you do now. I got a PB aged 44 at the half-marathon (1:23:04), 10K (37:08) and then marathon (2:54) distances. Just after my 45th birthday
steep climb can also cause sore calf muscles or even long-term injury. Kleanthous suggests walking as much as possible while on holiday, as most of us spend far too much time in everyday life sitting in front of a computer or behind the wheel of a car
