4-Day Santa Rosa Marathon Training Plan

Santa Rosa, CAAugust 22, 2027

Four runs per week for 18 weeks: two easy runs, one midweek aerobic run, and one long run. The schedule stays fixed; the guidance below shows how to choose terrain, rehearse conditions, and prepare for the Santa Rosa Marathon course.

The Santa Rosa Marathon starts at 6:30 a.m. on 4th Street beside Old Courthouse Square, follows the Santa Rosa Creek Trail and the Prince Memorial Greenway out of downtown, swings into wine country, and at one point runs you straight through the barrel room at DeLoach Vineyards before bringing you back to finish where you started. 1,349 people finished the marathon in 2025, and it has been selling out.

Your complete Santa Rosa Marathon schedule

The 18-week window opens around April 18, 2027. 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 Santa Rosa 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 Santa Rosa Marathon

Train for the Santa Rosa Marathon as a heat race with a flat profile, because that is what it is. With a 6:30 a.m. start and an average high near 82F, anyone slower than about 3:30 finishes in noticeably warmer air than they started in. The race falls in late August, so your peak training weeks land in exactly those conditions. Use them rather than hiding from them.

Specifically, run your last long run and at least two marathon-pace efforts starting at 9 or 10 a.m. rather than at dawn, so you know how your pace behaves as the temperature climbs. Then build a fluid and electrolyte plan around the aid spacing of 1.5 to 2 miles and rehearse it exactly. Heat plans fail on execution, not on knowledge.

For the terrain, the 416 feet of climb comes as small rolls through vineyard roads rather than as any hill worth naming. Practice holding steady effort while your pace drifts on gentle grades, and get comfortable with an effort-based race plan you can adjust downward if the morning is warm.

Last, rehearse a congested start. Do a couple of long runs on a busy multi-use path at goal effort and accept that the first mile or two will be slow. Runners who surge to get clear of traffic on the creek trail spend that money twice.

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

Do several Santa Rosa Marathon long runs on uninterrupted flat ground. With few terrain changes to reset your stride, steady pacing and late-run form matter more than hill speed.

Rehearse race morning

Race morning in Santa Rosa typically starts near 56F under partly cloudy skies with almost no wind, and the day climbs to an average high near 82F against an average low near 53F. That is a large swing in a single morning, which is the defining fact of racing here. Train through the summer heat rather than around it, and do your key marathon-pace work later in the morning so a warm finish is familiar rather than a shock.

Prepare for the hard part

The last 6 miles, run somewhere between 9:30 and 11 a.m. on an August morning in Sonoma County, when the cool start is long gone and the temperature is heading toward a typical high near 82F.

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 April 18, 2027 without forcing the early weeks.

Santa Rosa Marathon questions, answered.

When should I start this 18-week Santa Rosa Marathon plan?

The 2027 Santa Rosa Marathon is scheduled for August 22, 2027, so the 18-week window opens around April 18, 2027. 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 Santa Rosa Marathon course?

Do several Santa Rosa Marathon long runs on uninterrupted flat ground. With few terrain changes to reset your stride, steady pacing and late-run form matter more than hill speed. Train for the Santa Rosa Marathon as a heat race with a flat profile, because that is what it is. With a 6:30 a.m. start and an average high near 82F, anyone slower than about 3:30 finishes in noticeably warmer air than they started in. The race falls in late August, so your peak training weeks land in exactly those conditions. Use them rather than hiding from them.

Is four days a week enough to train for the Santa Rosa 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 Santa Rosa Marathon hot?

It can be by the finish. The 6:30 a.m. start is usually near 56F, but the day climbs toward an average high near 82F, so anyone running slower than about 3:30 finishes in noticeably warmer air. Do your marathon-pace training later in the morning so the second half is not a surprise.

Do you really run through a winery at the Santa Rosa Marathon?

Yes. The course routes runners through the barrel room at DeLoach Vineyards as part of its wine country section, which is one of the few marathons anywhere that takes you indoors mid-race. The rest of the wine country miles run on quiet rolling roads between vineyards before the course returns to downtown Santa Rosa.
