This moderate, 55.4-mile loop circles Lake Washington and Lake Sammamish and finishes with a quick spin across Mercer Island. Start at Gas Works Park and merge onto the Burke-Gilman Trail, following it north through the University of Washington campus. After 7 miles, cruise past Matthews Beach Park and continue north roughly 5 more miles to Tracy Owen Station Park and the northern edge of Lake Washington.
From here, the route rounds to the east and merges onto the Sammamish River Trail. At mile 17, the trail curves south and travels another 6.5 miles to Redmond; you'll leave the trail in Redmond and follow Redmond Way and Lake Sammamish Parkway along the eastern edge of Lake Sammamish. At the southern tip of the lake, the route veers west and follows the I-90 Trail onto Mercer Island, then back to Seattle. The final 6.5 miles of the ride follow Martin Luther King Way and Lake Washington Boulevard back to the Burke-Gilman Trail and Gas Works Park.
