Those looking for more jogging or cycling mileage must first endure a short drive (~10 to 15 mins.) to this gem of a spot.
The Burke-Gilman/Sammamish River Trail is approximately 27-mile paved path that follows an old railroad right of way around Lake Washington.
Closest access and parking to Downtown is Gasworks Park on the north shore of Lake Union. Heading north from there will keep you running till the path ends in Redmond - about 25 miles later!
