Yesterday, I ran the Army 10 Miler and developed either a cramp or pulled a muscle but I can't tell which. My training for this race didn't go as planned due to a bad case of bronchitis right in the middle of training, so I wasn't fully prepared for the race. However, I did get in a few long runs along with normal mileage the last few weeks. Topping out with a 8 miler last week. The race started off great. I was going strong, not over doing it though. Everything seemed on track for a great finish and PR. Around mile 6 I noticed some slight discomfort at the bottom of my hamstring (where the tendon and muscle meet) but I didn't think much about it and kept going. Also, I follow Galloways run/walk method and was doing 2.5/1 for this course. Several times I stopped and did some stretching (mostly for my calves and achilles tendon). Around mile 7.5, when I was switching back to running mode, I got about 10 seconds in and had a sharp pain at that spot, back of the knee hamstring tendon area. I stopped, did some more stretching and tried again. Same deal. Over the next .5 mile I tried to stretch it out and get back to running but at mile 8 I decided to just walk the rest of the race. It slowly increased to where I was hobbling more than walking at the end. I went to the medic tent and the doctor wasn't sure if I'd cramped or if I'd pulled a muscle. When I got home, I stretched every half hour or so and iced it. The pain is still there today, not near as bad, but still present. Today feels different than yesterday, more like I over did it than the sharp pain I had yesterday.
My question, does this sound more like cramps or a pulled muscle? I just signed up for the Shamrock Marathon in March and have a few weeks to relax before starting training. I want to make sure and do what I need to not have this happen during the marathon. Any suggestions as to cramping or pulled muscle, and what I should do to avoid it?
