I know a lot of people think I'm too competitive, but I like to look at my competitiveness as motivation. I don't think I would be as good of a runner or a business owner or engineer if I wasn't competitive.
Today I did my run with new purpose. I even got on my bike and did the workout I missed (skipped) last week. So thank you, fast chicks, for motivating me to become a better runner.
PS- I'm not doing this to go out and beat people, by the way. I feel motivated to make myself the best runner I can be. Just wanted to clarify. :)
