Injury and Last minute training

On the penultimate long run before the taper (28th March) something went in my leg behind the knee and couldn't run the damn thing off, and called the cavalry to pick me up (I was 10 miles into a circular 22 so a long way from home). Went for a sports massage on it, something bad on the tendon from my hamstring into my bone. Rested for 3 weeks, and was planning some smaller runs this weekend when back from hols. With the holiday extended because of the flight groundings did a few runs in Tenerife. Leg hurt a bit, but nothing too bad, and by the third run on Monday (up a great mountain) it felt as good running as not. Its aching a bit today, but I think it should be OK for Sunday, so here we go. No more running now, rest, pasta and then lots of sports drinks.
