Cottage Grove Half Marathon

Saturday, August 15, 2020 – Sunday, September 13, 2020 • Cottage Grove, OR • Course Map

Note: The 2020 race is a virtual event to be run between August 15 and September 13. Registration details are included below.

The Row River Trail, a 15.6-mile trail in western Oregon, is the highlight of the Cottage Grove Half Marathon, which will observe its 5th annual running in 2020 to benefit the United Way of Lane County.

The point-to-point course begins on Row River Road at Dorena Elementary School. From there, runners head west on Row River Road, taking a right to continue on that path for about a mile. Right after mile 1, the course continues onto the Row River Trail for the majority of the race.

While running the half marathon along the abandoned rail line that became the Row River Trail, runners will get the chance to observe nature and history, passing such natural landmarks as Dorena Lake before crossing the finish line in downtown Cottage Grove.

The course is fast with few uphill segments, race organizers note; in fact, most of the elevation on the course is downhill. The half marathon will be open for four hours, making the course accessible to walkers as well as runners.

A shuttle to take runners to the start line is available, with parking available near the finish line.
