Can anyone help me. I have just started out within the last few weeks. I'm not a natural runner but would like to use it as a way of keeping fit losing weight etc. I'm trying to build up slowly, everytime I've come back home I end up in a coughing fit that goes on for a long time afterwards and end up losing my voice. I am a non smoker never tried it. Is this normal to have this happen or is it something else? In addition to this the last few times my legs are sessions up in cramp in my calves. How's best to prevent this from happening agan and what's the most effective cause of action to relieve me from it now. I went late afternoon yesterday and still have a lot of pain in them now. Could this be more in relation to technique or running shoes being the wrong type. Can any of you give me and indication of the best to move forward with this?
