knee pain

4 weeks ago i ran 3 x races in 7 days :- A 5 mile race on a mondayevening ,  a Park Run on the Saturday and Newbury 10k on the sunday -  My plan was to use the Park Run as a gentle training run in between the two races, but i saw someone that used to work for me (  dismissed ! ) so i went for it eyeballs out like an idiot !  

Since then i have had knee pain and after the Penn Seven on sunday i have bit the bullet and been to a Physio...

Its turns out my left calf is bigger than my right calf and is causing my left knee to inflame !  I know have a series of exercises to complete each day to right the wrong !

My view :- do something early

Rudders, a word of warning.  I had similar symptoms about 7 years ago.  It started when I tweaked something in my knee while running up stairs at work.  It was a bit sore for a couple of weeks or so, then it felt ok again (or so I thought).  Fast forward 16 months and many miles later, the tendon snapped.  My initial pain was due to straining the tendon (didn't know it at the time).  Sometimes on runs, my knee would lock momentarily.  Each time it did, I was putting more strain on the tendon.  It might just be a bit of tendonitis and hopefully, rest and physio will sort it out.  All the same, get it checked out as a precaution.
