Trail running
As of 2015, this network of parks and trails is still expanding. Metro, the regional government, plans to link the 40-Mile Loop to trails along the Willamette River to Wilsonville, south of Lake Oswego. The regional government has also proposed connecting Wildwood Trail to the partly completed Westside Trail running north–south through Washington County to the Tualatin River. Another planned trail would extend the Springwater Corridor along a proposed Cazadero Trail to Barton on the Clackamas River. Longer-term goals include trail links to the Sandy River Gorge Trail east of Gresham and the Pacific Crest Trail, which runs from Mexico to Canada and follows the Cascade Range through Oregon.
