At registration, indicate which school you are running for. This is optional — runners not affiliated with an Ivy League school are welcome to enter and will receive an official finish time.
Each Ivy League school's three fastest finishers are scored. Their finishing positions become the team's points. Any number of runners from a school can enter — only the top three count toward the team score.
The three finishing positions are added together. The school with the lowest total wins.
Runners from outside the Ivy League are fully welcome — they compete for individual finish times only.
