Mr. Brightside,

Received! Thanks for the tip.

As for not quitting, I'm completely sold on that already, but there are times when even my high pain tolerance is tested and if my knee plays up halfway through this race (assuming I can train enough to compete) then all the codeine in the world won't help me for the last 30 miles. Well, it might.

Anyway, off to the physio when I can get an appointment so I will report back when I find out what's wrong.
