Tolt Pipeline Fat-Ass 50K, 26.2, 13.1 & 1.5

Woodinville, WA 50K, Marathon, 1/2 Marathon, 1.5 Miler

Registration closes: Fri, Jun 29 @ 11:59PM


No official race (that we know of) runs on the Tolt Pipeline trail. We don't want to change that, instead we are organizing an unofficial "Fat-Ass" style 50K, Marathon & Half-Marathon on the east section of the Tolt Pipline Trail. Start is near the baseball fields off 145th in Woodinville. We'll use sections of the trail both east and west of the Sammamish River. Enjoy all the beauty the Sammamish River valley has to offer. Course is a half-marathon distance. Do it twice for a marathon OR two times plus an out and back on the Sammamish River Trail for the 50K. Both the 50K and Marathon will have 2,600 feet of gain and you get to run up Heart Attack Hill twice! For those of you looking for something short and quick, run the 1.5 mile Heart Attack Hill Challenge. Let see who can get up that hill the fastest! Set an FKT for these courses or win your Strava segment, if you are into that kinda thing. Or just come out for the fun of it all!

Registration is free, but we ask you to sign a waiver and bring food to contribute to the cause, and consider bringing a new pair of socks or a t-shirt to donate to YouthCare. Run with us and then hit the wineries in Woodinville afterwards for a fun day in the Sammamish River Valley.

Course Maps

PLEASE NOTE: Puget Sound Energy is doing construction on the Tolt Pipeline east of Avondale Road. Construction has started, so we have different route than originally advertised. You are not missing anything! You will still climb Heart Attack Hill, you will still get miles and miles of open carriage trail and views of the Cascades and the Olympics. The only difference is we'll use a portion of the pipeline trail to the west of the Sammamish River.

Experience the steepest part of the course without continuing on for the longer races. Stick around and support participants in the longer runs: Heart Attack Hill Challange Map


There is a public use parking lot on North side of NE 145th Street and the east side of the Sammamish River. Link to map of parking area If you arrive early for the event, there should be plenty of parking at 7:30am, but the lot does fill up due to youth baseball games and wine-country traffic so don't cut it close with getting arriving just in case you have to go hunting for parking.

What to Bring

We have no entry fee for this event, and ask that you bring food and/or beverages to share with the group. Can be something small like a plate of cookies or a bag of chips. We will also be collecting donations of new socks or t-shirts for YouthCare: at the event.
