Swim Course
Adriatic sea swim off the Jesolo coast
The 1.9 km swim takes place in the Adriatic Sea off the Jesolo beach. This is open-water sea swimming with potential for light chop depending on conditions. Water temperatures in early May typically sit around 17–19°C — wetsuit-legal and cool. The beach start and finish make for a straightforward course with good spectator access.
- Adriatic Sea swim — open water with potential light chop
- Wetsuit-legal in early May — cool Mediterranean waters
- Beach start and finish on the Jesolo coast
- Single-loop course with clear buoy sighting
Bike Course
Flat and fast through the Venetian countryside
The bike course heads inland through the flat agricultural landscape of the Venetian hinterland. This is one of the flattest 70.3 bike courses in Europe — the terrain is pan-flat with virtually no climbing. The challenge comes from wind exposure on the open agricultural roads and the need to maintain focus on a course with few landmarks. Strong cyclists can put up very fast splits here, but the flat terrain means no freewheeling descents to recover — you're pedalling the entire time.
- One of the flattest 70.3 bike courses in Europe
- Agricultural roads through the Venetian countryside
- Wind exposure on open flat terrain
- Constant pedalling — no descents for recovery
Run Course
Beachfront run along the Adriatic
The run course follows the Jesolo beachfront along the Adriatic coast. The terrain is flat and fast, with sea views throughout and crowd support concentrated near the finish area. The two-lap format means you experience the atmosphere twice, with the energy of the finish area lifting athletes on both passes.
- Flat beachfront course along the Adriatic
- Sea views throughout the run
- Two laps with concentrated finish area support
- Fast course — PB potential on fresh legs
Race Day Conditions
Pleasant early Italian summer — warm and calm
Early May in Jesolo offers warm but manageable racing conditions. Air temperatures range from 14–23°C with low humidity and typically light winds. The Adriatic coast benefits from a mild maritime influence that prevents extreme heat. This is one of the more weather-friendly 70.3s on the European calendar — comfortable for racing without the heat stress of later-summer Mediterranean events.
