The Charleston Marathon no longer runs a full 26.2. The event continues as the Charleston Half Marathon and Shrimp & Grits 5K, so the course notes below still describe roads you can race — just not over the marathon distance.

Course & elevation
Charleston is flat and coastal from start to finish, threading the Lowcountry’s marshes, neighborhoods, and historic peninsula. There is no real climbing, with the route staying at sea level and only the faintest of rises over rail crossings and the odd overpass. The reward is a scenic, point-to-point line that ends among the antebellum homes, steeples, and cobblestones of the old city.

What you pass
- Miles 4 to 5: around the Battery at the tip of the peninsula
- Mile 15: turnaround in Riverfront Park, 115 ft west of the cement foundation
- Miles 21 to 23: the Park Circle loop
Worth knowing
- On Viaduct Rd runners stay in the north-side lane, with cones placed on the dashed lines.
- On the east side of Riverfront Park runners follow the crushed rock path.
- The course was measured using the full width of the road and the shortest possible route unless noted otherwise.

Key moments
- Mile 1–8Out through the upper neighborhoods and Lowcountry roads, flat and open; lock into goal pace early.
- Mile 13–20The middle miles roll past marsh views and residential streets, exposed in places, so mind any breeze and keep the effort even.
- Mile 24–26.2Onto the historic peninsula past steeples and cobblestone blocks for the finish, a scenic close on flat ground.
Pacing strategy
A flat point-to-point that rewards a patient, even effort. There are no hills to plan around, so the focus is holding pace through any exposed, breezy stretches in the middle miles. Run the tangents on the point-to-point line and resist banking time early; the flat finish pays off a controlled first half.
Pacing by goal time
Checkpoint splits for four common goals at Charleston 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 | 20:366:51/mi | 24:027:59/mi | 27:289:08/mi | 30:5410:16/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 Charleston 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 Charleston Marathon splitsFueling & hydration
Aid stations roughly every 1.5–2 miles with water and sports drink. Mild Lowcountry humidity can mask sweat loss even on a cool day, so drink steadily and keep gels on a fixed schedule rather than waiting for a low.
Weather
Mid-January Charleston is usually cool and pleasant for racing (40s–50s). Coastal humidity or a brisk onshore wind off the harbor can both factor into the exposed stretches.
What race morning has actually been like
The last 5 editions of Charleston Marathon, measured at the start line rather than averaged across the month. Starts have run 41–66°F, averaging 51°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2016 | Jan 16 | 52°F | 51°F | 36 mph | 57°F |
| 2017 | Jan 14 | 53°F | 58°F | 15 mph | 62°F |
| 2018 | Jan 13 | 42°F | 37°F | 51 mph | 43°F |
| 2019 | Jan 12 | 41°F | 43°F | 27 mph | 49°F |
| 2020 | Jan 11 | 66°F | 63°F | 55 mph | 69°F |
Dew point has reached 63°F (2020). 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 (Saturday in mid-January (2nd Saturday 2017-2020; 3rd Saturday in 2016); race discontinued after 2020), observations at Charleston, SC (start).

Is Charleston Marathon a good Boston qualifier?
Yes. Start and finish sit at the same elevation, so no downhill adjustment applies and 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.
Compare every course, how the downhill bands work, or work out your own target.
