I've had an enforced break, as my left knee gave up the ghost about 10 days ago. Back to it today with a knee support, feeling a bit nervous, as I had heard this run was a bit of a killer and had the BEST RUN ever! After an awkward start, managed to get into a good rhythm and pace. I realised I was using a really short stride, and lengthening it, it really helped. Not sure how the knee has faired, it normally starts hurting later in the day, but hopefully the knee support will have helped. So all in all I think the rest has helped and I haven't completely lost all of the fitness I have built up. Good luck to anyone else taking on W6R2!
