Hi, I'm new, keen to get going but don't know where to start. I get very nervous about running outside, I feel very self conscious because I am really overweight. If and when I do go out for a run I will walk to a secluded spot and then run when I know there is nobody to see me. If someone then appears I stop and walk until I am alone again. I want to get over this fear but don't know how. Help!
