12-Week Atlanta Marathon Training Plan

Atlanta, GAMarch 7, 2027

Start around December 13, 2026. The calendar below gives each phase a real date, then the course guidance shows where to make the build specific to Atlanta Marathon.

The Atlanta Marathon is being rebuilt. Atlanta Track Club has moved the race to a new date in early March and put it on a new course, and the detailed routing has not been published yet. What has not changed is the ground underneath it. Atlanta sits on a set of ridges, and a marathon that stays inside the city has to go over them.

Does this window fit your starting point?

Use this window when your recent training is steady and the opening week will not be a mileage jump. If you are returning after a long break, twelve weeks is too little room to rebuild and peak at the same time.

  • Your weekly mileage has been consistent for the last six to eight weeks.
  • You have completed recent long runs and do not need to rebuild from three easy miles.
  • You can protect the same number of run days from week one through race week.
  • You are prepared to begin race-specific work early instead of using a long base phase.

The 12-week Atlanta Marathon calendar

These dates define the job of each phase. Your current mileage, recent longest run, experience, goal, and available days still decide the actual workouts inside them.

Settle

Weeks 1–2

Dec 14, 2026–Dec 27, 2026

Hold close to your current volume, establish the weekly rhythm, and make sure the opening load is honest.

Build

Weeks 3–7

Dec 28, 2026–Jan 31, 2027

Grow the long run and weekly work with step-back weeks intact. There is no room to repay missed mileage.

Peak

Weeks 8–10

Feb 1, 2027–Feb 21, 2027

Complete the most race-specific long runs, rehearse fueling, and practice the terrain that will decide the final 10K.

Taper

Weeks 11–12

Feb 22, 2027–Mar 7, 2027

Reduce volume, keep the routine familiar, and arrive on race day without trying to squeeze in one more big week.

Make the window specific to Atlanta Marathon.

Course-specific work starts early in a 12-week build. Put the race's terrain and expected conditions into long runs once the opening weeks feel controlled, without adding extra hard days.

How to train for the Atlanta Marathon

Train for the Atlanta Marathon on rolling terrain at goal effort, not on a flat loop at goal pace. This is a course where climbing arrives in repeated moderate doses rather than at one summit, so the thing being tested is your ability to hold steady output while the numbers on your watch move around underneath you.

Build the long run on a route with a rise every mile or two and run it without surging on the ups or coasting on the downs. Check your breathing, not your splits. If your pace drops forty seconds on a climb and your effort hasn't changed, you're doing it right.

Then train the descents on purpose. A returning loop hands you as much downhill as uphill, and the late-race descents are where quads that only ever saw flat ground start to give out. Two or three sessions of controlled downhill running in the final six weeks, quick cadence and no braking, will change how mile 22 feels.

Because you can't know the exact route in advance, do your specificity work by profile rather than by street. Continuously rolling ground, no long flat stretches to hide in, and the last hour rehearsed on tired legs will cover any version of this course.

12-week Atlanta Marathon plan questions, answered.

When should I start a 12-week Atlanta Marathon plan?

The 2027 Atlanta Marathon is scheduled for March 7, 2027, so the 12-week window opens around December 13, 2026. Treat that as the outside edge of the window, then line week one up with the plan's normal weekly rhythm.

Is a 12-week plan long enough for the Atlanta Marathon?

Use this window when your recent training is steady and the opening week will not be a mileage jump. If you are returning after a long break, twelve weeks is too little room to rebuild and peak at the same time. 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 Atlanta Marathon course in 12 weeks?

Course-specific work starts early in a 12-week build. Put the race's terrain and expected conditions into long runs once the opening weeks feel controlled, without adding extra hard days. Train for the Atlanta Marathon on rolling terrain at goal effort, not on a flat loop at goal pace. This is a course where climbing arrives in repeated moderate doses rather than at one summit, so the thing being tested is your ability to hold steady output while the numbers on your watch move around underneath you.

What if the 12-week Atlanta 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 Atlanta Marathon a hard course?

Yes. The Atlanta Marathon climbs through a city built on ridges, and the elevation arrives in repeated moderate doses rather than one big hill, which makes it hard to pace. Boston qualifying rates sit in low single digits: 1.9% of finishers in 2026, 5.3% in 2024. Plan to run slower here than on flat ground.

Is the Atlanta Marathon course changing?

Yes. Atlanta Track Club has moved the race to a new date in early March and announced a new course. Detailed routing has not been published, so older mile by mile descriptions and elevation profiles describe a route that is being replaced. Check the organizer's course page before you plan splits or pick out landmarks.

Each page counts back from race day, maps the 4 phases to real dates, and applies the window to that course and its typical conditions.
