Ok, so Mr Wheels has just told me that a sign in a local vets says that there are Adders where I run. Yikes! He asked Dr Google who says if you get bitten, keep still. Not much help as I will be keeping still miles away from home/another living person. Of course it's the dog who is most likely to be bitten but the advice is to keep him still and head for the vets...Running carrying an 8 stone dog is really not in my training programme!
I have thought about twisted ankles, dog attacks and weirdo's in the woods but SNAKES???
