Discouraged

I've been told to not give up and to hang in there and that it will get better ... but I am fed up with not being able to run as fast and as long as I want to. It's discouraging to hear about other people who with very little training can run miles with 2 fingers up their nose.

I don't think I will quit - I'm nothing if not a stubborn blob - so what else is there to do except put on the shoes and try, try again? Maybe Recluse would like to come with :)
