I have developed a pain in the back of my knee after a 19km run yesterday. It hit me in the last 10 metres of my run. From reading up on RW it appears to be a hamstring strain. Have to admit I'm not very good at doing my stretches after a run, especially hamstring ones. Do lots when i run in the gym during the winter but they seem to fall by the wayside over the rest of the year when I run outside.
Which hamstring stretches do you recommend? Which give the best results?
