Well, that's torn it...

I've been training quite a lot recently for a race at the end of the month - Offa's Orror - and for once, actually following some vague training schedule with the view to not only getting around the course, but also putting in a good time.
Things have been going well and I've been getting some serious mileage (well, serious for me!) done. So, all was looking good for a 17k run on Sunday afternoon. Indeed I covered off the first 5km of the run averaging a very comfortable and sustainable 5m 15 per km. Nothing outstandingly good, but it's a pace I'm happy with. Then, as I rounded the corner up onto Chiswick Bridge my calf/achilles went tight, very tight and then 'pop' in under 5 paces. And yes, I do mean 'pop'. It was a very peculiar sensation, which was then replaced by a deep and intense flash of pain.
So, there I was, at the furthest point that my route takes me from home, unable to run, in a light running top and shorts... and then the wind picked up and it started to rain. Things weren't looking good. Fortunately I could atleast hobble, so long as I didn't try to put any power through my right foot and so started the hour-long walk home, and damn, did I feel miserable.
Once home I put my leg up and used firstly my newly re-aquired (long story involving helping my ex move flat on the saturday) ice pack and then a hot water bottle to treat the area. Today I managed to hobble into the office, but I suspect that 2 weeks is not enough time for it to heal enough to be put into a 20k cross country race in Wales.

Anyone want to take my place on the race? Ticket, transport and accomodation organised...
