Other than doing the corporate challenge about 10 years ago, this was my first "race". I went in hoping to finish in about 40 minutes since I've been jogging 4.5-4.7 mph on the treadmill. But I actually finished in exactly 35 minutes. There were a few points where it was so crowded I had to walk, and I partially walked up 2 steep hills, so I feel great about my time. I finally went to a running store and had a gait analysis and bought a pair of the shoes they suggested - if anyone has not done this I highly recommended it! I feel like it made a huge difference.
My town has a big 10K in September so I'm going to slowly increase my distance(will try to run 2X/week) until I can do it comfortably, then work on the speed.
So glad I did this!
