What is the NASCAR Challenge Series?
The Challenge Series is the second national series run by NASCAR México. It shares the calendar with the headline NASCAR Mexico Series, racing on the same weekends at the same tracks, and it has its own drivers and its own winners. For a visiting fan that means a NASCAR weekend in Mexico puts two national series on the same bill. Check the promoter’s ticket page for what a given weekend ticket covers.
Because the two series run together, everything on our Mexico Series pages (venue guides, ticket prices, how to get there) applies to the Challenge Series too.
