The choice of yours I disagree with is the choice to call yourself slow
Don't identify yourself as such, You're way faster than the person who chose to sit on the sofa and watch tv reruns. Running is a mental game. You're a runner. Not a fast runner, not a slow runner. Just a runner. It's an awesome thing to be!! Pat yourself on the back and go run. If you find that you have more time per mile to enjoy your surroundings than some other runners. consider yourself lucky <grin>
