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.
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 — a small late incline on the return.
- Mile 13Where the half splits off — 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.

Fueling & 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 — 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.
