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 Houston 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

Oct 26, 2026–Nov 8, 2026

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

Build

Weeks 3–7

Nov 9, 2026–Dec 13, 2026

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

Peak

Weeks 8–10

Dec 14, 2026–Jan 3, 2027

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

Taper

Weeks 11–12

Jan 4, 2027–Jan 17, 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 Houston 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 a January marathon

Your peak weeks land in November and December: cool, friendly running weather, and a calendar full of everything else. The winning move is a plan that fits your actual week so the holidays bend around training instead of breaking it. Stride matches on your schedule and experience for exactly this reason.

Train rhythm for race day: long runs with sustained goal-pace segments are the highest-value Houston session. And practice race-morning cold: Houston Januaries often start near freezing and warm quickly, so rehearse layers you can shed.

Let your current training decide the actual plan.

Current mileage, recent longest run, marathon experience, goal, and available days determine which plans rank first. After you choose and subscribe, Stride dates every workout through January 17, 2027.

12-week Houston Marathon plan questions, answered.

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

The 2027 Houston Marathon is scheduled for January 17, 2027, so the 12-week window opens around October 25, 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 Houston 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 Houston 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. Your peak weeks land in November and December: cool, friendly running weather, and a calendar full of everything else. The winning move is a plan that fits your actual week so the holidays bend around training instead of breaking it. Stride matches on your schedule and experience for exactly this reason.

What if the 12-week Houston 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.

How long do I need to train for the Houston Marathon?

Most Stride marathon plans run 12 to 20 weeks, which for a January race means starting in the fall. Get matched in the app and Stride maps every week from today through the holidays to race day.

Is Houston a fast course?

One of the fastest big-city courses in America: essentially flat, single loop, and run in cool January air. It's a favorite for PR and BQ attempts for good reason.
