About our data
Startline USA is an independent directory of running races in the United States. This page explains where the information comes from and how to tell us about a mistake.
Where the information comes from
Race dates, distances, fees and registration status come from the organizers’ own websites and from published race calendars, including RunGuides. Each race page links to the official page for that race.
How often it is updated
Listings are refreshed on a regular schedule, and every race page shows the date it was last checked. Dates, prices and availability can change at any time, so check the official site before you register or travel.
What you may not find here
Not every race is listed, and some details, such as exact start times, fees or map positions, are not available for every race. When a detail is missing we leave it out or show “Not listed”.
Report a correction
Spotted something wrong or out of date? Use the “Report a change” form on the race page, or write to us at support@startlineusa.cc.
