Named in honor of Dave Pengelly, a local Missoulan and avid outdoorsman and frequent hiker in the mountains where the race takes place who passed away in 2003, the Pengelly Double Dip Trail Half Marathon takes runners through the twists, turns and challenging ascents and descents of Missoula’s Mount Sentinel and University Mountain, the majestic mountain peaks that lie just to the east of the University of Montana campus.
