Course & elevation
Miami is essentially flat, with the only grade coming from the causeway bridges that carry the course over Biscayne Bay. The MacArthur Causeway right after the start is the biggest of these, followed by a second span onto Miami Beach and a return over the scenic Venetian Causeway. A couple of short South Miami Avenue bridges late are the only other rises.

The certified route
A complex loop from downtown Miami: out across the MacArthur Causeway to Miami Beach, back via the Venetian Causeway, south through Brickell and Coconut Grove with an out-and-back on the Rickenbacker Causeway, finishing on Biscayne Blvd at Bayfront Park.

- Biscayne Blvd at NE 8th St, even with the south edge of the NE corner crosswalk, in front of the American Airlines Arena.
- Finish
- Biscayne Blvd in front of Bayfront Park, 34 ft 3 in south of the south edge of the first storm drain south of Flagler St.

Key moments
- Mile 0.25MacArthur Causeway, the largest bridge on the course, climbed while you’re still fresh.
- Mile 2.5Second causeway span onto Miami Beach and a run up Ocean Drive.
- Mile 8–11Venetian Causeway back to the mainland, with a small late incline on the return.
- Mile 13Where the half splits off and the full continues south as the field thins.
Pacing strategy
Don’t spend yourself on the early causeway bridges. Climb them by effort and let the flat stretches do the work. The bigger challenge is the warmth and humidity once the sun is up, so run conservatively and prioritize hydration over splits in the back half.
Pacing by goal time
Checkpoint splits for four common goals at Life Time Miami 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 | 20:446:46/mi | 24:127:54/mi | 27:399:02/mi | 31:0710:09/mi |
| Mile 6.2 | 41:236:57/mi | 48:178:06/mi | 55:119:15/mi | 1:02:0510:25/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 Life Time Miami 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 Life Time Miami Marathon splitsFueling & hydration
Aid stations roughly every 1.5–2 miles with water and sports drink. The pre-dawn start and Florida humidity mean heavy sweat losses, so drink early and keep gels on a fixed schedule rather than waiting until you feel low.
Weather
Late-January Miami is usually mild but humid (60s–70s°F), and a warm, muggy morning is the main threat to a goal time.
What race morning has actually been like
The last 5 editions of Life Time Miami Marathon, measured at the start line rather than averaged across the month. Starts have run 66–73°F, averaging 71°F.
| Year | Date | Start | Dew pt | Wind | By late morning |
|---|---|---|---|---|---|
| 2020 | Feb 9 | 71°F | 63°F | 14 mph | 74°F |
| 2022 | Feb 6 | 66°F | 68°F | 1 mph | 73°F |
| 2023 | Jan 29 | 73°F | 65°F | 14 mph | 77°F |
| 2024 | Jan 28 | 73°F | 72°F | 11 mph | 78°F |
| 2025 | Feb 2 | 72°F | 71°F | 6 mph | 77°F |
Dew point has reached 72°F (2024). 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 (variable late-January/early-February Sunday (2021 cancelled)), observations at Miami, Florida (start). Source: Open-Meteo historical reanalysis (ERA5), 7-11am local at the start line. Reanalysis is modelled from station observations, so treat it as a close record rather than an official one.

Is Life Time Miami 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.
