Quitting smoking may shorten your race times and extend your life.
Pat asks: I am very embarrassed to admit this, but I'm a runner who smokes about 10 to 15 cigarettes a week. I have recent PRs of 3:18 marathon, 1:32 half marathon, and a 19:02 5K. Would my times greatly improve if I stopped smoking?
You are not the only runner ...
