Tens of millions of people participate in endurance events in the United States each year, and across the country people dedicate their lives and earn their livelihoods from the creation of those events. Despite the size of the industry, there is no singular aggregator of data for those events.

This annual report seeks to provide practical information about the state of the industry, including demographic shifts, pricing trends, marketing effectiveness and fundraising best practices. In 2021, we reviewed the rate of recovery from COVID-19, lingering changes in event participation, and surprisingly normal patterns of registration.
