Boulder Sunset Run - Boulder Reservoir, Colorado
The Boulder Sunset Run is a weekend road running event presented by BBSC Endurance Sports at Boulder Reservoir in Boulder, Colorado. The event features two measured race distances and is part of BBSC’s summer endurance program.
Both courses are out-and-back and are described as flat and fast. Each route includes a crossing of the Boulder Reservoir dam and finishes with a slight downhill section. The organizer lists multiple on-course fuel opportunities placed at or near mile markers to support runners during the race.
Distances:
- 5K course, out-and-back, flat and fast.
- 10K course, out-and-back, flat and fast.
The organizer provides separate fueling arrangements for each distance: the 5K course includes two fueling opportunities located at or near mile markers, while the 10K course includes six fueling opportunities at or near mile markers. The event material notes standard race logistics and safety oversight from the race director as an organizational priority. Visit the organization's website for the most recent information.
