Course & elevation
The Mississippi Gulf Coast Marathon is genuinely flat, running point-to-point along Highway 90 right beside the Gulf of Mexico with the beach and water in view for much of the way. There are essentially no hills, only the gentle crowns of the road, so pacing and wind end up defining the course. Cool December air and the dead-flat profile make it a legitimate PR and Boston-qualifying option.

Key moments
- Mile 1–10Flat coastal road beside the Gulf. Settle straight into goal pace and resist going out too fast.
- Mile 13–20More flat highway with the water alongside. Watch for a coastal headwind and tuck into groups.
- Mile 24–26.2A flat finish along the shore, where a disciplined even effort closes strong.
Pacing strategy
With no hills to dictate effort, lock onto goal pace from the first mile and hold it. This is an even-pacing course where discipline, not terrain, decides your time. Watch the Gulf wind: if it’s blowing, draft off other runners on the exposed highway stretches and save the energy for a steady finish.
Pacing by goal time
Checkpoint splits for four common goals at Mississippi Gulf Coast Marathon. These are effort-even rather than pace-even: the paces shift with the course profile, so climbs are slower and descents faster by the amount the grade actually costs. For any other goal time, use the planner below.
| Checkpoint | Sub-3:00 | Sub-3:30 | Sub-4:00 | Sub-4:30 |
|---|---|---|---|---|
| Mile 3.1 | 20:366:52/mi | 24:028:01/mi | 27:289:10/mi | 30:5410:19/mi |

Splits assume even effort and are adjusted for this course's climbs and descents, which cost more than they give back. A model, not a promise: wind and heat move real splits around. See how the pacing model works.
Plan your mile splits
Turn your goal time into a mile-by-mile plan for Mississippi Gulf Coast Marathon, built from this course's elevation. The even pace approach comes pre-selected, and grade-adjusted pacing evens out your effort across the climbs and descents.
Plan Mississippi Gulf Coast Marathon splitsFueling & hydration
Aid stations roughly every 2 miles with water and sports drink. The uninterrupted flat rhythm makes a fixed gel schedule easy to keep, so fuel on time, and bump fluids if the coastal humidity is up despite the cool air.
Weather
Early-December on the Mississippi Gulf Coast is usually mild and good for racing (starts often in the 40s–50s°F), with coastal humidity and an onshore wind off the Gulf as the main race-day variables.
What race morning has actually been like
The last 5 editions of Mississippi Gulf Coast Marathon, measured at the start line rather than averaged across the month. Starts have run 48–65°F, averaging 59°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2021 | Dec 12 | 48°F | 39°F | 34 mph | 53°F |
| 2022 | Dec 11 | 65°F | 66°F | 20 mph | 69°F |
| 2023 | Dec 10 | 62°F | 61°F | 51 mph | 62°F |
| 2024 | Dec 15 | 61°F | 64°F | 29 mph | 68°F |
| 2025 | Dec 14 | 60°F | 60°F | 35 mph | 60°F |
Dew point has reached 66°F (2022). Above about 60°F, sweat stops evaporating efficiently and most runners lose pace no matter what the thermometer says. It is the number to watch here, not the air temperature.
Dates derived from the race's published pattern (2nd Sunday in December (weekend of the second Sunday, after Thanksgiving)), observations at Pass Christian, MS (start).

Is Mississippi Gulf Coast Marathon a good Boston qualifier?
Yes. The course drops 1 ft net, comfortably inside the 1,500 ft threshold where Boston's downhill adjustment begins, so a time here is submitted as run.
This drop is our estimate rather than a figure from the course's certificate. If it sits near a threshold, confirm with the organizer.
