1. Start with public event sources
We collect event facts from organizer and track websites, their public calendars and feeds, and registration platforms such as MotorsportReg. A listing may link directly to registration or to an official calendar when an individual event page is unavailable.
Our coverage depends on which sources we can read reliably. Some publish a full season; others release dates gradually or use pages our tools cannot currently read. We do not cover every organizer or every track day.
2. Make schedules easier to compare
We organize dates into a consistent format, normalize known track names and locations, assign organizer and vehicle categories, and reduce duplicate records. The website uses those fields for search, sorting, and location filters.
This processing can make mistakes. A name match or category is not a guarantee of the track configuration or eligible vehicle. The organizer's event details remain the source for those decisions.
3. Check whether a listing is usable
Our publication checks look for a usable title, organizer, date, location, and public link. We filter incomplete records and flag recognized conflicts between an event date and a date in its link. Upcoming-event views also filter out past dates.
These are automated checks, not a manual verification of every event. A correctly formatted link can still be outdated, and a listed event may sell out, move, or be canceled after we collect it.
Before you book
- Confirm the current date, track layout, and registration status at the official source.
- Check vehicle eligibility, experience-group availability, and preparation requirements with the organizer.
- Follow the event link to book. The organizer or registration provider handles payment and refunds.
- Our calendar is not live inventory. We do not currently show a verified last-checked timestamp for every listing or promise a fixed refresh interval.
4. Handle unavailable sources carefully
When a source fails or produces unusable results, we can pause collection from it. A failed refresh does not, by itself, mean that organizer canceled its events. Existing listings may remain until they expire or are corrected, so check the official source.
5. Review suggestions and corrections
For a new listing, send the event name, date, organizer, track and location, vehicle type, and official event or registration URL. For a correction, identify the listing, explain what changed, and include a source that supports the change.
Messages go to NTD for review. They do not automatically update the calendar, and a submission is not a registration or a guarantee of inclusion. Contact the organizer directly for urgent questions about attending an event.
