TEAMS: At least three people are needed to form a team in the 5-mile race. However, teams may have more than 3 people. Using the cross-country method to calculate team time, the times of the top 3 runners on your team will be calculated to get your team time. Awards will be presented to the Fastest three teams. Awards will also be presented to Top Friends & Family Fundraising Team and Top Corporate Fundraising Team.

SCHOOL TEAMS: Organize your school to participate. All registered participants will be counted- including 5-Mile, 1-Mile and volunteers - for eligibility for Top School Trophy. This is a traveling trophy which the winning team will house at their school for the year.
