Listed events have been approved by ACU. In addition to ACU Listed Events, the calendar includes World and Continental Championships relevant to Canadian National Teams.

Race directors complete an application in order to list their event and agree to abide by the ACU Event Listing Policy (in development). However, ACU has no means to ensure events are conducted within a certain standard. Runners should personally review an event's safety, risk management, and other policies to determine whether they wish to participate.
