I can't say that it was well-organized because the running space was too damn narrow for me. I lost momentum and got a side stitch... It sucked big time! Too many people, too little running space.
My goal was to match my 10k pace or better. Unofficially, I ran 41 minutes. Better than the 10k pace. Running on the treadmill is totally different from running outdoors. You get extra help n the treadmill and it's flat. Your knees won't hurt after.
During the race, all I was thinking was to keep on running. I realized that I was actually running away from the sadness I had and headed to something new. It was good motivation actually. :)
