Alfa 10 Hour Regularity Relay
The Alfa 10 Hour Regularity Relay is a team event conducted at Winton Raceway, Victoria in mid to late October each year.
Each team consists of 3 to 5 drivers, each usually with their own car, and numerous support and pit crew. Each driver nominates a personal target time and during the event they attempt to score by producing lap times close to, but not faster than, that target time. The team whose drivers produce the best combined score will win the event.
