Since outside assistance is allowed, pits are included to provide a consistent area for this to occur. A pit to the right of the course is normal since most riders dismount to their left. In larger events a separate pit lane is featured so only those wishing a new bike or other assistance need enter the lane (this type was debuted at the Zeddam, Netherlands World Cup of January 1999). In some cases pits are provided in two different parts of the course.
