It had to happen I guess, I've suffered my first sports related injury!
During my walk/run today I've really pulled my calf muscle. I upped my running and then sort of felt it 'go' and am now hobbling around feeling sorry for myself. See, I knew there had been a good reason not to run these last 20+ years! I now have to rest it - apparently it can take up to 4 weeks to heal and I was doing so well. I'm hoping I'll be able to walk again in a couple of days without the pain.
