IMPORTANT: All 100-meter events must be done between noon ET October 26, 2012, and noon ET October 27, 2012.


Make sure you have:

• A pre-measured, level course with a clear start and finish line

—If the course is not on a running track, the course must be measured and marked out by a qualified person who is not associated with the organization holding the event. The independent witnesses can serve as that qualified person.

—If the course is not completely level, then the 100-meter event must be completed going uphill.

• Two Independent Witnesses* to observe the entire process, confirm the exact and final number of participants, and verify that all rules were followed (download the required fill-in-the-blank Witness Statement)

• Enough Stewards* along the course to observe participants, ensure full participation by all involved, and note any participants who need to be deducted from the final total (download the required fill-in-the-blank Steward Statement)

• An approved counting method in place that the Indepdendent Witnesses will observe. Approved counting methods include:

—Clickers: two people with clickers at the entrance

—Ticket stubs

—Logbook (not recommended for groups of 100 or more): Participants print and sign their names; Independent Witnesses must countersign the completed logbook.
