A definite improvement with the calf muscles. Signed up for a cut price 3 month membership of the E. Riding Council gym in Withernsea. Includes access to the gym, swimming and classes. The Gym instructor who did my induction wants to try running so I recommended C25k ! They will work out a fitness plan for me to get me back on track with the running. Lots of helpful advice re calf muscles (they have a foam roller). Feeling better about it, for anyone else who has had a setback, don't give up !
