Hi. New to running. Started nearly 3 months ago. Started doing run/walk method then got virus/allergy for 4 weeks and couldnt breathe!! Started running again and then got knee problem. Things finally started to improve. Last two runs - 1.5 miles - 14mins, 1.76 miles 17 mins, without stopping, not got up to 2 miles yet. Dont know if these are good times or bad? I'm 41 and never really done any exercise before.
