4-Day Mississippi Gulf Coast Marathon Training Plan

Biloxi, MSDecember 13, 2026

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 Mississippi Gulf Coast Marathon course.

The Mississippi Gulf Coast Marathon runs point to point along the Gulf shoreline from Pass Christian to Biloxi, and the organizer's own description is the honest one: a fast, flat, Boston qualifier friendly path with unobstructed beach views past the coast's historic homes. Unobstructed is the operative word. The course sits between about 6 and 54 feet of elevation with roughly 163 feet of climbing.

Your complete Mississippi Gulf Coast Marathon schedule

The 18-week window opens around August 9, 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.

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 Mississippi Gulf Coast 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 Mississippi Gulf Coast Marathon

Train the Mississippi Gulf Coast Marathon for wind and for pacing without terrain cues. With about 163 feet of climbing across a point to point coastal road and unobstructed exposure the whole way, the two skills that decide your day are holding goal effort into a headwind and holding goal pace when the ground gives you no feedback at all.

Do the wind work deliberately. Find an exposed road, a levee, a beachfront, an open farm road, and run marathon pace intervals into the wind rather than with it. Most runners naturally turn to run with a tailwind and then never rehearse the hard direction. Twenty minutes at goal effort into a real headwind, twice a month, changes how the middle of this race feels.

For pacing, build long runs on flat, straight, featureless routes. The specific discomfort of this course is mental: mile after mile of the same view with no hill to mark progress. Practice breaking a long run into blocks by time rather than by landmark, because on race day there will be no landmark.

And be ready to abandon your goal pace for goal effort. If the wind is against you, running your planned splits into it will cost you the last ten kilometers. Set an effort target in training and learn what it feels like, so that on race day you can run it whether the clock cooperates or not.

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 Mississippi Gulf Coast 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 on the Mississippi coast in mid December typically starts near 59F under overcast skies with humidity around 87% and a northerly around 7 mph, with an average high near 62F and a mean around 53F. That is mild and damp rather than cold, and the day barely warms. The humid air is the thing to train for, so keep some long runs in muggy morning conditions rather than waiting for crisp weather.

Prepare for the hard part

Miles 18 through 24 into a coastal headwind, where a flat course offers nothing to hide behind and no change of terrain to reset your legs.

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 August 9, 2026 without forcing the early weeks.

Mississippi Gulf Coast Marathon questions, answered.

When should I start this 18-week Mississippi Gulf Coast Marathon plan?

The 2026 Mississippi Gulf Coast Marathon is scheduled for December 13, 2026, so the 18-week window opens around August 9, 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 Mississippi Gulf Coast Marathon course?

Do several Mississippi Gulf Coast 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 the Mississippi Gulf Coast Marathon for wind and for pacing without terrain cues. With about 163 feet of climbing across a point to point coastal road and unobstructed exposure the whole way, the two skills that decide your day are holding goal effort into a headwind and holding goal pace when the ground gives you no feedback at all.

Is four days a week enough to train for the Mississippi Gulf Coast 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 Mississippi Gulf Coast Marathon flat?

Yes. The Mississippi Gulf Coast Marathon runs between roughly 6 and 54 feet of elevation with about 163 feet of total climbing, and the organizer describes it as a fast, flat path along the coast. The difficulty is not terrain. It is that a fully exposed shoreline gives you no shelter from wind for 26.2 miles.

Is the Mississippi Gulf Coast Marathon a good Boston qualifier?

The course is certified and genuinely fast, but recent qualifying rates are modest. 5.1% of finishers ran a qualifying time in 2025 and 3.7% in 2024, down from 9.6% in 2023 and 16% in 2021. Flat and cool December conditions help, so the course is not what is holding those numbers down.
