Montrail Ultra Cup

The 2015 Black Canyon 100K will be part of the Montrail Ultra Cup. The top two (2) female and top two (2) male finishers will automatically qualify for entry into the Western States 100 event. In the case that the first, or second place participant is already in Western States (or decides to opt out), the automatic bid will slide to third place, fourth place, and subsequently down to fifth place as needed (no places below fifth will be accepted). There will also be a “last chance” slot selected by lottery for one finisher of the race who was not selected in the general Western States 100 lottery this past December.
