I finally managed to do wk5r3 on Wednesday last week and I felt so good. Next day my hamstrings felt tight so I kept stretching then when I could but it didn't seem to go. Saturday I ran wk6r1, which I found really easy. No pain in the hamstrings so I thought all was good. Today, Monday, I get up and almost fall down as this pain shot through my hamstring. It was like an elastic band snapping in my leg. It was painful to walk on for a while but then it went. Then, at random moments it does it again. It's so painful I cry out then walk like I've broke my leg.
Anyone else had this? What should I do? I'm sure to walk 5k on Sunday for pilgrims hospice with some friends.
