Coach Joel recorded the amount of time his runners take to run a mile in practice. If, on average, they can run it in under 7 minutes they will go the Disney World race; if they can stay under 8 minutes they will go to the New York City race; and if they can stay under 9 minutes they will go to the Hawaii race.

• Hawaii

• Atlanta

• Disney World

• New York City
