Boulder Reservoir - Trail Running
A loop trail/road run totaling 5.3 miles around one of Boulder’s most popular summer recreation spots.
From the Eagle Trailhead runners can easily access the Sage Trail for additional miles.
Destination Distance From Downtown
With minimal elevation gain and well groomed paths throughout, the reservoir poses minimal technical challenge.
Time To Complete
The 5.3 mile circuit is well maintained and should take roughly 45 minutes to complete when running at an 8:00 minute/mile pace.
The trail and road are well maintained, making the circuit available year round, though the reservoir is much livelier during the summer months.
Dogs are not allowed in the park May 15 through Labor Day.
Parking is free at trailheads, but you'll have to pay to park inside reservoir grounds.
