20-Week Yakima River Canyon Marathon Training Plan
Ellensburg, WAApril 3, 2027
Start around November 14, 2026. The calendar below gives each phase a real date, then the course guidance shows where to make the build specific to Yakima River Canyon Marathon.
The Yakima River Canyon Marathon runs a single road. You start on Canyon Road just south of the Berry Road intersection outside Ellensburg, follow the Yakima River downstream on State Route 821 through the canyon, and finish in rural Selah near the canyon's mouth. 190 people finished it in 2026.

Does this window fit your starting point?
Use the longer window to make the early build calmer, not to add five months of hard training. The plan should begin close to your current load, hold most running easy, and delay the biggest race-specific work until the middle of the cycle.
- You want a longer foundation phase before marathon-specific training.
- Your current mileage is steady but below the load you expect to carry later.
- You prefer gradual long-run growth with regular step-back weeks.
- You can sustain a five-month routine without turning every week into a peak week.

Make the window specific to Yakima River Canyon Marathon.
Build general durability first. Add the race's hills, flat sustained running, downhill exposure, heat, or humidity in layers after the weekly rhythm is stable, then make the final long runs the most course-specific.
Read the full race guideHow to train for the Yakima River Canyon Marathon
Train for the Yakima River Canyon Marathon by running on effort rather than pace, and by preparing both directions of gradient. The course drops 292 feet net but climbs 779 along the way, so it wants climbing legs and descending legs, and the constant curves mean your GPS splits will lie to you all morning.
Put sustained climbs late in your long runs rather than early. Two major hills on a net-downhill course arrive when your quads are already loaded from descending, which is a completely different sensation from climbing fresh. Run the hill at mile 16 of a long run, not at mile 4.
Train the long downhill finish separately. End two or three long runs on a sustained descent at goal effort, short quick steps, no braking. On this course that final drop is either free time or the place where your quads finally give out.
Then train the solitude. With 190 finishers in 2026 you may not see another runner for miles, so do at least four long runs alone at goal effort, no group and no one to chase. Generating your own pace in silence is the specific skill this race asks for.

20-week Yakima River Canyon Marathon plan questions, answered.
When should I start a 20-week Yakima River Canyon Marathon plan?
The 2027 Yakima River Canyon Marathon is scheduled for April 3, 2027, so the 20-week window opens around November 14, 2026. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.
Is a 20-week plan long enough for the Yakima River Canyon Marathon?
Use the longer window to make the early build calmer, not to add five months of hard training. The plan should begin close to your current load, hold most running easy, and delay the biggest race-specific work until the middle of the cycle. The course does not change the opening load you can handle, so choose from your current mileage and recent longest run before adding race-specific terrain.
How should I prepare for the Yakima River Canyon Marathon course in 20 weeks?
Build general durability first. Add the race's hills, flat sustained running, downhill exposure, heat, or humidity in layers after the weekly rhythm is stable, then make the final long runs the most course-specific. Train for the Yakima River Canyon Marathon by running on effort rather than pace, and by preparing both directions of gradient. The course drops 292 feet net but climbs 779 along the way, so it wants climbing legs and descending legs, and the constant curves mean your GPS splits will lie to you all morning.
What if the 20-week Yakima River Canyon Marathon window has already started?
Do not double weeks or cram missed mileage into the remaining calendar. Use your current mileage, recent longest run, experience, goal, and available days to choose a plan that can enter at an appropriate point while preserving the taper.
Is the Yakima River Canyon Marathon downhill?
Net downhill, though the climbing is real. The course drops 292 feet net across 26.2 miles while gaining 779 feet and losing 1,071, and the organizers describe two major hills along the way. Treat it as a rolling canyon road that happens to finish lower than it starts, not as a descent.
How big is the Yakima River Canyon Marathon?
Small. 190 runners finished the marathon in 2026, up from 122 in 2025 and 65 in 2024, and there is no cap on marathon entries. Expect long stretches with nobody in sight. That is a selling point for some runners and a serious problem for anyone who races off other people.
