As of April 2020, our site has complete statistics for this tour for 2009-present. We are optimistic we can add a few more complete seasons for 2006-2008 in the near future. 1999-2005 will be mostly complete, but we know there are a few races that will be incomplete and need help finishing. If you can help provide this missing information, please contact us.


The series' 2020 season was cancelled in its totality due to the COVID-19 pandemic.
