Got to say that after just looking through the Wikipedia article about it I am beginning to question why I am doing this again... am hoping that if I can run without pain I'm not doing any further damage...
I have the Chronic Exercise variety in my right anterior calf. It came on in Nov 2011 a couple of weeks after I had run in that year's Abingdon Marathon.
Jim, I've work Falke RU3s for years which have got me through 6 marathons and all of the training without ever giving me a blister - tried 1000 double layers and didn't like.
Appreciate it's all horses for courses though.
Have been focussing on my running style to keep the compartment syndrome at bay since returning to running in December after 14 months complete rest. can feel it in the background but okay. Before the rest literally couldn't run 1/2 mile without stopping in agony.
Signing up to a 1hr workshop this weekend with the "Running School" local to my home which may offer a few more pointers to pain-free running.
Baldbloke, get in touch with the organisers, Abingdon have previously operated a waitlist. You should be able to join that and still have a good chance of getting in. They also permit private transfer of entries as well. All is not lost.
If you manage to get in, it is a nice small mara and suitable for a first timer.
