Co-drivers at the Bathurst 1000 are required to complete a minimum of 54 laps during the race. This is approximately one-third of the 161-lap race distance, as the race itself is 161 laps long (about 1000 km). The minimum lap requirement ensures that co-drivers participate significantly but still allows teams the flexibility to decide their own strategies regarding driver stints. Typically, co-drivers do more than 54 laps, often around 61 or more, depending on fuel stops and team tactics. Teams have to balance giving co-drivers enough time to meet the requirement, while also maximizing the performance of their primary drivers.
