i have struggled most of the year with stiff calves. i try to keep myself hydrated and haven't upped my training to quick. i suffered in Jan,Feb, some of March and recently in July. Got new shoes(Asics gel-nimbus 9s) and tonight ran in them for first time. noticed a little improvement in calves, it starts when running uphill, which living in Sheffield hills are non negotiable . anyone got advice? never suffered with calf problems before.
