Included in the Winter 2015 issue of Trail Running Canada is an article I wrote called "Ski Your Way to Better Running" (p. 37). And if cross-country skiing just isn't your thing, you should still check out the e-mag - it's full of lots of great content. (Back issues of this fantastic publication are available here.)
I'm happy to report that my sacrum is healing up nicely and it should only be a few more weeks before I'm back to all my usual activities. Until then, I'm keeping busy - and sane - with water running and walking/jogging on the treadmill. Hopefully, I'll be able to add skiing to that list after this weekend.
