Hi all. Have been a graduate for a couple of months now. On the whole, it's great. Dropped a stone, have managed 5k in under 30, and I've been out to 7k on occasion. Am running 3 - 4 times a week, really loving it, so all is good. Almost. The problem is in the title. I live in a hilly area, and my knees are really starting to suffer, particularly the morning after a hilly run. Classic 'under the kneecap pain', worse on one leg. I'm desperate to continue the progress i've made. So.... Do I run through it, hoping my knees are getting stronger? Do I stop for a fortnight? Do I seek medical advice? Anyone had the same problem and got through it? Any helpful tips, very gratefully received.
