Only riders who hold the nationality of the country for the purposes of the  present regulations may compete for the title of national champion and the relevant  points. A rider cannot compete for the title of national champion and the relevant points  for more than one country during the same season.  If a national federation organises a separate event to award the national champion's title  in a given category, riders in this category may not take part in the national championship  event in another category. As an exception, if a national federation organises separate  events for the award of the Elite and U23 national road champion titles, the national  federation may determine that U23 riders are authorised to take part in both events.  A maximum of three national federations may organise their national championships as  a joint event.
