2025 Event!

Register for this one early, because it sells out! 50M / 50K / 25K / 10K are hosted on Saturday. Sunday is 50K / 25K / 10K (no 50M). The Saturday race sold out in February last year! We have strict permit limits at this event, so if you want to run Saturday (especially with a group of friends) we strongly recommend you register before February. We do NOT do a waitlist for the event. You MUST register for the "Late Start" category using the registration button above.

New for 2025! We've added 100 spots for a "late" start 25k/10k that starts at 11:00AM. Sleep in, or use the morning to drive in from the west side and hit the course later in the day. We've added this option to increase event capacity, while managing trail congestion (most 10K/25K runners will be off the trails by this time). So if you like lazy mornings, this option is for you!

Race Day Registration

If there are spots available we will hold race day registration. If the event is sold out we will not.

Experience the Magic of Ancient Lakes!

Come experience the magic of the Ancient Lakes in the heart Washington Desert in this unique trail race! These trails are truly spectacular and will allow you to experience the best the desert has to offer, taking you on a journey through canyon-like gorges, along the shores of ancient desert lakes and to the base of cascading waterfalls. You will feel like you are in the desert southwest but with a Washington flare. With a distance for everyone, and the same great support and swag you have come to expect from Run Super Series events, this is an event you won’t want to miss at this exciting new venue!

Course Description

With a unique cloverleaf design, our scenic course will allow you to experience the best of the Ancient Lakes area. The larger 25k loop features 3 smaller loops, each beginning and ending at a common aid station. The 25k loop features about 2,200’ of rolling up and down, with no single climb or descent more than 400’. The trails are primarily single track. The first loop will take you to the a spectacular waterfall and then run along the shores of the Ancient Lakes. The green loop will run out to yet another lake and feature a return trip through some canyon like desert terrain. The blue loop will drop you down into the Columbia River Gorge, and have you run along the river before climbing back out and rolling to the finish line. The 50k will run the 25k course twice and the 50M will run the 25k course three times. The 10k course will run on portions of the red and green loop and will have about 1,000’ of elevation gain. Trails are primarily single track.

25K will hit the aid station 2x at 4.7 and 10.1 miles. 50K will hit the aid station 5x at 4.7, 10.1, 16.2, 20.9 and 26.3 miles. 50M will hit the aid station 8x at 4.7, 10.1, 16.2, 20.9, 26.3, 32.4, 37.1 and 42.5 miles.
