text: Individual time trials are often used as stages in stage races such as the Grand Tours; these vary from short prologue time trials over no more than eight kilometres (designed to create an attacking racing style earlier in the race)  to longer distance events over flat or rolling courses, to timed ascents of mountain roads (mountain time trial).[citation needed]
