We need a prediction contest. Give us your picks here. You must be logged in to win.
Pick the winners of the men's and women's races and winning time. Whoever is closest wins. Do the same for the American men and women.
Whoever is closest in each contest wins a Supporters Club membership and free LRC shirt (super soft running shirt).
If you're already a Supporters Club member, we'll extend your membership a year.
