The Boulder 5 Mile:

The Boulder Spring 5 Mile starts at 9:00am sharp on Sunday, May 4th. The

Boulder 5 Mile is a race course that is custom tailored to the dirt roads north of the Boulder Reservoir. Whereas the old 10k course forced runners to travel west on (paved) Niwot Road, now the 5 Mile turns around just before our runners/walkers get to Niwot Rd. Therefore the entire 5 Mile course is on the Boulder backroads dirt roads. No pavement! Once participants arrive at the turnaround previous to arriving at Niwot Rd. they'll then proceed back to the Boulder Reservoir and finish in the same place they started. Perfect for rookie and experienced runners alike!


Needless to say, the 5 Mile is a good distance for any 5k or 10k runner. But it's also a good distance for the marathoner or half marathoner that might not be up for the full or half on race day. All participants in the 5 Mile receive the same race items that the marathon and half marathoners receive (except the marathon/half marathon finishers medals).
