I'm a real runner now -- I must be because I have the scars to prove it. :) I've been running regularly for just over 3 1/2 years and tripped/fell for the first time this morning.
I had to cross a 4-lane road as a part of my route. Nothing new -- it's pretty hard to run more than a short distance without crossing a road here. As I approached the road, I saw a car coming from the left. No problem because I could just turn left and run against traffic until I could cross safely. When the car passed, I headed across, had to cross the median, looked right to be sure nothing was coming from the other direction, and looked back ahead to see that I was about to tangle with another runner coming from my left (it was dark and I think each of us surprised the other). We dodged each other quite easily and I started stepping up over the curb onto the sidewalk. Suddenly, I pitched forward and my knees met the curb and my hands (gloved) met the sidewalk. As I fell, I felt that my foot had caught on something and heard whatever it was move -- it sounded like a piece of plywood.
I hopped right up and ran on -- my knees hurt but I only had a half mile remaining. Funny enough, I actually felt energized. Boy, it hurt, though. I got back and found that my running pants are now ventilated on one knee. I'll have some bruises but so far am not too sore.
Otherwise, it was a pretty decent (though cold) run.
Run well, y'all,
