I will start with a little history of why this possible injury is sadly exciting. About two years ago I decided to start running to get in shape that was not round. I started off running all the time and quickly re aggravated a past knee injury. After a month off, I started wearing knee sleeves on both knees. I also realized that I could not run more than two days in a row before my knees were so painful I could not walk.
Finally about six months ago I accidentally left my knee sleeves at home and ran a 5 mile run. I had no problems that day or the next. Even though I still wear the sleeves I know I do not need them but they make me feel comfortable. I ran many times without them with no problems since the initial oversight.
This weekend I ran three days in a row. My knees are fine but my hamstring did not make it. Day 1 was a slow flat 6 mile run on concrete. I slowed my pace to 11 minute miles since I was going to do a race the next day. The race is where the problems started. It was a 10K trail race on trails I am very familiar running. The first three miles were at a good trail pace of about 10:45 minute miles. Then it hit me, a huge cramp in my hamstring. I massaged it and continued. Twenty minutes later same hamstring cramped again. I stopped stretched and continued. I felt fine after the race but my pace went up 4 minutes per mile the last 3.4 miles.
My hamstring was sore the rest of the day but I thought nothing of it. The next morning was a very slow 3.5 mile trail run with the local running club. I had no problems during the run but the rest of the day I had problems every time I bent my leg. I am also sore today and it is painful to stretch.
The good news is that I can finally run three days in a row. I can also up my mileage to prepare for the half marathon in April. It will be my first. The bad news my hammy is possibly strained.
