Aye I considered giving it a miss tomorrow Dannirr, but regardless of if I did run or not, I'm still clueless as to what I should be doing between now and April 7th. As I say, I've tried everything I can think of in the past, it just seems to be 'the luck of the draw' on the day if the SS play up or not!
Hi Bedders - can I dare to suggest there's nothing 'luck of the draw' about your shin splints, it's just that you don't YET understand what is triggering them. It's important that you accept it is not random pain but it works in a consistent way. It is simply an accumulated overload injury which responds well to rest and is provoked by exercise stress. There is a pattern. Long term it requires strengthening of the dorsi-flexor muscles (like ATM and Wi hinted at). Lots of walking around barefoot with your toes in the air! Good luck mister.
PC91 - well done on bagging your first 20 miler. A major milestone.
As for my race yesterday, went with the (non-white T-shirt) which seemed about right. Details here or here.
Extremely muddy with some killer hills. Needed my trail shoes, didn't have them! Was a struggle to stay upright and to push when your feet are slipping & sliding. Was amazed to complete the course upright. Pushed hard to 8k then eased off a bit. Was taken by 11 guys in the first easy km. Just didn't want to overdo things in my first proper race back.
Picked up the effort again around 10km and finished well, pulled back 3 places. 12.2km in 51:36. Official results in the southern end of Belgium seem to arrive by bicycle courier via Patagonia, but I think I was about 65th from 700+ runners. Not too shabby then but I will go faster 
Happy long running today and remember, it will be better weather and more pleasant in Paris in what... 28 days!
