Western States 100 is the final event each year in the Montrail Ultra Cup series. The top three male and female winners of each event, 50 Miles and over, receive an automatic entry invitation to Western States. If either the first, second, or third place finisher is already entered in Western States, then the fourth place finisher will receive the automatic entry invitation. The automatic entry will not slide down further than fourth place. Montrail Ultra Cup winners will receive their invitation via email and have two weeks from the qualifying race to complete the registration, including paying the entry fee.
