Will I ever run again?!

[Ry]. Ok, so on Monday physio gave me the all clear to run again. How long has it been??!! 5, 6 weeks now?? I was all excited, only to be sick with a major headcold by Monday night. Two days in bed, finally back at work yesterday, feeling pretty miserable. Will attempt my first run tomorrow - all 20 mins of it. Will I ever get back into my marathon training?? Things could be worse....
