Last night my optimism of the other day went up against reality and was found wanting.
Following an almost twinge free, gentle 4 miles on Wednesday night my right Achilles gave out last night forcing me to walk/hobble 2 miles back to the changing rooms.
So its back to the ice pack supported with eccentric training (heel lowering) and some gym work to try to maintain my general fitness until I can get back running.
(please note that this is an objective description of things. I don't think I can put into print how I really feel about it)
