Well wouldn't you bloody know it. I sailed through the 9 weeks of C25K without any mishaps to my legs or back and suddenly without warning, my right calf has tightened up and feels like it's in a vice!
My wife massaged it last night (deep tissue which was agony) and I awoke feeling fine. Went for my run this morning - a shorter one than usual, just to see if this calf flared up again - AND IT DID! So I think I'm out of action until it calms down. It's extremely frustrating as it started without warning yesterday as I got off a train to go for a job interview. As Victor Meldrew might say "I DON'T BELIEVE IT!"
So the bad news is, I'm out of action for a bit running wise. The good news is (I'm a freelancer) I got the job I was interviewed for. Hooray, mixed with a bit of damn and blast!
