About This Race
The 50-mile option provides a substantial ultra challenge without the extreme commitment of the 100-mile distance. This middle-ground distance allows runners to experience the course's variety while testing their endurance capabilities over a demanding but manageable timeframe. The distance appeals to runners stepping up from shorter ultras or those seeking a challenging one-day effort.
The courses utilize a combination of clockwise and counter-clockwise loops centered around Danish Pass and the Highline Trail. The Papa Bear 100-mile follows the most complex routing, beginning with the 50-mile course clockwise to Danish Pass, then completing a counter-clockwise loop before reversing the entire 50-mile route. The terrain features technical singletrack through high mountain forests, with significant elevation changes and challenging navigation points that require focused attention from runners.

Notable Features
This race offers the unique opportunity to experience the original Bear 100 course that operated for nearly a decade before the current Bear 100 moved to a different location. The multi-loop format and complex routing create a technical navigation challenge that separates this event from more straightforward ultra courses. The intimate field size and mountain lodge start/finish at Deer Cliff Inn provide a throwback atmosphere to ultrarunning's earlier, more grassroots era.
