Help - How long until Exercise stops Hurting???

Thank you everyone, makes me feel so much more motivated already.  I had booked an appointment with exercise Physiologist but thought going to a PT would be enough (plus I am sooo over all the appointments!), but now I think I will rebook and do both.
@Jane-Altona - good luck with the marathon, make sure you let us all know how you go.  Hopefully you will also enjoy a bit of a holiday at the same time.
