Two months ago I reached the dizzy heights of W2R1 (followed by an ill advised W2R2 4 days later) and was brought to a standstill by knee pain that kept me awake at night and even caused me to take a couple of days off work. Didn't I start this program to become more healthy? hmmmm.
Several people told me running was probably not for me. They had knee pain and were told running was out of the question. After all, I had knee surgery 8 years ago, clearly I wasn't cut out to be a runner.
BUT ... googling knee problems I found this forum and met all you lovely people. And from nowhere came a stubborn determination that this would not be my end. I read your posts on a daily basis from the injury couch. I followed suggestions on this forum: I paid to see a physio a couple of times (lots of exercises to build up that leg which it turns out had never built up to match the other since the earlier knee injury and surgery), I did my exercises, I rested until it healed, I did all 5 weeks of Strength and Flex and as soon as we returned from holiday I restarted at W1R1; I went slowly, I took two rest days between runs, I wore a knee support to run and I used ice after each run.
And last night I (slowly and cautiously) completed W3R1. No knee pain. I was (am) over the moon. There is absolutely no way I would have found the determination without this forum. Thank you so much to everyone who posts here. Good luck to everyone, and fingers crossed I will keep going a bit longer.
