Flat, warm, and fast on the Florida panhandle

Swim Course

Warm Gulf of Mexico waters off Panama City Beach

The swim takes place in the Gulf of Mexico off Panama City Beach. Water temperatures in May are warm — typically 23–26°C — making this potentially non-wetsuit legal in warmer years. The Gulf is generally calmer than the Atlantic, with gentle swells rather than breaking surf. The beach start means a sand run into the water, and the single-loop course offers straightforward navigation.

Bike Course

Flat coastal roads through the Florida panhandle

The bike course is flat — this is coastal Florida with virtually no climbing. The route heads through the panhandle on straight, open roads. The main challenge is wind exposure: the flat, open terrain offers no shelter, and Gulf breezes can build through the morning. Athletes should ride on power, not speed — tailwind sections feel fast but headwind sections will come. The flat profile suits time trialists and steady-state riders.

Run Course

Beachfront run in the Florida heat

The run follows the beachfront through Panama City Beach. The terrain is flat and the views are pleasant, but by May, the Florida heat and humidity become significant factors. The combination of warm temperatures, Gulf humidity, and limited shade means cooling and hydration strategy matter as much as run fitness. Athletes coming from cooler climates should plan accordingly.

Race Day Conditions

Warm and humid — Florida in May

May on the Florida panhandle means warm, humid racing. Air temperatures range from 20–30°C with high humidity. The Gulf breeze provides some relief but also creates wind on the bike. Afternoon thunderstorms are possible but typically arrive later in the day. Athletes should prepare for warm conditions with increased fluid and electrolyte intake.
