“As the name implies, this trail is mainly made up of doubletrack along the Tolt Pipeline.”— Trail Run Project Staff
The first mile of the run from Blyth Park is a mile up singletrack trail. I would suggest trail shoes for this part. The rest of the run is wide dirt path under power lines so there is enough room to run w/ a group. A tricky part is finding your way over I-405 but once you do, it is really quite easy. This set of rolling hills makes for a great training run and definitely will work your legs.
The most popular section of this trail begins at what is known as Heart Attack Hill, just by Redhook Brewery coming off of the Sammamish River paved trail, and ends just before the very steep descent to Sammamish Valley (approximately 7 miles).
