I haven't run since I was in primary school, but about a month ago I decided to get fit. In my first run I just about made it to the end of my road and had to walk back
But now I already feel fitter and can run further without getting so tired. Whereas before I would stop because my lungs were about to explode, I am now stopping because my lower legs (not so much my calves but the part directly opposite them - I have no idea what they are called) hurt so much.
The other day, I'm late for my train so I run about 20 seconds to catch it - not out of breath in the slightest

- would have been breathing heavly all the way home a month ago), but the front of my legs ached like anything - it hurt walking up the stairs for the rest of the night for crying out loud!?!
Now I want to get fitter, but I feel like my lower legs are holding me back. I knew that there would be pain but it feels like I'll do myself an injury if I continue pushing. Is there a way I can strenghten this part of me? Or do I have to push through this pain to strengthen them up??
Cheers
