Australian National Time Trial Championships
The Australian National Time Trial Championships, are held annually with an event for each category of rider: Men, Women & under 23 riders. The event has been run concurrently with the Australian National Road Race Championships since 2002. The Australian Championships have officially been known as the Scody Australian Open Road Cycling Championships since 1999, taking the name of their main sponsor, but are more commonly referred to as The Nationals. The under 23 time trial championships were introduced in 1998.
The winners of each event are awarded with a symbolic cycling jersey featuring green and yellow stripes, which can be worn by the rider at other time trialling events in the country to show their status as national champion. The champion's stripes can be combined into a sponsored rider's team kit design for this purpose.
