Your complete Seattle Marathon schedule

The 18-week window opens around July 26, 2026. Weeks one through 17 keep the normal Tuesday, Wednesday, Thursday, and Sunday rhythm. Only race week moves so the marathon lands on its actual weekday. If the window has passed, do not skip ahead or cram missed mileage into the time left.

Open any week to see all seven days. Week 1 is open to start.

Race

Marathon — 26.2 mi

This free plan is complete, fixed, and ready to use.

It begins at 15 miles per week, peaks at 40, and asks you to manage schedule changes and missed training yourself.

A Stride plan ranks from your running, then dates to race day.

Current mileage, recent longest run, marathon experience, goal, and available days decide which plans rank first.

How to use this plan for Seattle Marathon

The mileage builds your engine. Your long-run route, pacing, fueling, and clothing rehearsals make that fitness specific to this race.

How to train for the Seattle Marathon

Train for the Seattle Marathon by building repeat-hill durability and cold weather habits, not by bolting one big climb onto a flat plan. The course gains about 818 feet and loses about 908 in short pitches, all between roughly 11 and 211 feet of elevation, so your legs meet the same up and down cycle dozens of times.

The session that matters is a long run over continuously rolling ground where you hold effort steady and let your pace swing. Twenty to thirty seconds a mile in both directions is normal on this kind of course. Runners who chase an even split up every rise arrive at mile 20 with nothing left, so learn what goal effort feels like on a climb and hold that instead.

Do the descents deliberately too. There's slightly more descending than climbing here, and the drops come when you're already tired. Practice running downhill at goal effort with a quick, short stride rather than braking, so a late descent becomes somewhere you gain time instead of where your quads quit.

Then train in the cold and the wet on purpose. Late November mornings here start near 42F under cloud, and the gap between a good race and a miserable one is often just gloves you didn't throw away too early and a warm up you actually bothered to do.

Keep the plan honest. This free schedule contains no speedwork. Apply the course guidance through route choice and race rehearsal without turning easy days into extra workouts. If your goal calls for marathon-pace work, compare it with First Marathon Plus.

Match the terrain

Run part of your Seattle Marathon long-run mileage on terrain that rises and falls. Hold effort steady on climbs, let pace change, and practice cresting without surging.

Rehearse race morning

Race morning in Seattle has averaged about 42F with 87% humidity, overcast skies and a light southerly breeze, with the day topping out near an average high of 46F. That's cold enough that you'll be chilled at the start and never truly warm, and damp enough that wet clothing keeps pulling heat out of you. Run your long runs in the rain instead of moving them indoors.

Prepare for the hard part

We can't honestly pin it to one mile, because the organizers have revised the route in recent years, but the pattern holds: the climbs that break people here are the short ones in the last 10 miles, not any single named hill.

Check the starting line before you commit.

Beginner-friendly does not mean couch-to-marathon. Week one asks for four runs, 15 total miles, and a six-mile long run.

  • Fifteen miles in week one is close to the volume you already handle.
  • You can protect four run days most weeks, including a weekend long run.
  • Your priority is a steady first-marathon build without speedwork.
  • You can start around July 26, 2026 without forcing the early weeks.

Seattle Marathon questions, answered.

When should I start this 18-week Seattle Marathon plan?

The 2026 Seattle Marathon is scheduled for November 29, 2026, so the 18-week window opens around July 26, 2026. Weeks one through 17 keep the normal weekly rhythm and Sunday long run; only the final race week shifts to the event's actual weekday. If that date has already passed, do not compress 18 weeks of mileage into a shorter window.

How should I adapt the four-day plan for the Seattle Marathon course?

Run part of your Seattle Marathon long-run mileage on terrain that rises and falls. Hold effort steady on climbs, let pace change, and practice cresting without surging. Train for the Seattle Marathon by building repeat-hill durability and cold weather habits, not by bolting one big climb onto a flat plan. The course gains about 818 feet and loses about 908 in short pitches, all between roughly 11 and 211 feet of elevation, so your legs meet the same up and down cycle dozens of times.

Is four days a week enough to train for the Seattle Marathon?

Four run days can be enough when 15 miles in week one is not a sudden jump and you can protect the long run most weeks. This schedule builds to a 40-mile peak and a 20-mile long run. A runner chasing an aggressive time or already supporting more volume may fit a higher-mileage plan better.

Is the Seattle Marathon hilly?

Yes. The course climbs about 818 feet and descends about 908 while never getting higher than roughly 211 feet above sea level, which means constant short pitches rather than one big climb. It starts at Seattle Center at 7:00 a.m. and finishes at Pier 66 on the waterfront, so the ground between is all city hills.

What's the weather like at the Seattle Marathon?

Cold and damp. Race morning has averaged around 42F with humidity near 87% and overcast skies, and the average high for the day is about 46F. Expect to start cold, stay cool the whole way, and get cold quickly if you stop moving or slow to a walk.
