Trifun Pellworm: Course, Route Profile & Map

Course & Elevation

The swim covers 500 metres in the cordoned-off old harbour, swim caps compulsory and in North Sea water that, as the organisers warn, occasionally runs into transition itself. Transition sits right at the harbour, so the distances between disciplines are short.

Then comes the passage that defines the day: a single closed loop of around 19 kilometres along the inner dike toward the Nordermühle. Pellworm sits at or below sea level behind that dike, and the profile shows it. More than 95 percent of the bike course is flat, the recorded track stays inside a band from roughly two metres below to three metres above zero, and the whole lap totals 36 metres of gain. The terrain gives you no free coasting.

The closing run goes 2.5 kilometres toward the deep-water ferry pier and back along the same road to the harbour finish. With five measured metres of gain it is the flattest section of the race. The start falls in the early afternoon, so you run in the warmth of the day, and there may be sheep standing on the course.

Pacing Strategy

On a course without a single climb there is no natural change of rhythm and therefore no free recovery. Swim the harbour controlled, because there is almost nothing to win there and plenty to lose. On the bike only one number then matters: the power you can hold for 30 to 40 minutes without cracking.

What decides the race is the wind direction, not the route. On an open dike loop you inevitably get one long headwind section and one tailwind section. Ride the headwind part at a constant effort, by feel or by power meter, and resist the urge to win back the speed you appear to be losing. That is exactly where you burn the matches you will miss on the run.

The second trap is the transition. A pancake-flat five-kilometre run tempts you straight onto race pace. Run the first kilometre deliberately a touch under target pace and only open up after the turnaround.

Training plan for Trifun Pellworm: 12-week build

For the sprint distance on Pellworm, expect roughly 1:05 to 1:35 hours of racing depending on your level. The character is a hard, largely even effort just under threshold: no climb pushes you briefly over it, no descent lets you freewheel, just one continuous load across all three disciplines.

The race is decided in the headwind sections of the dike loop and in the first minutes after the transition to running. Both demand the same skill: holding a chosen intensity stubbornly even when speed and feel argue against it.

Training should therefore centre on longer threshold intervals on the bike, ridden to power or heart rate rather than speed, ideally in deliberately windy conditions and in race or aero position. Add tempo runs at your target five-kilometre race pace and regular brick runs straight off hard rides.

If you travel from inland, also practise open water in salt water, including sighting without lane markings, and prepare for an early-afternoon start: race-day fuelling and breakfast have to fit a 2 pm gun, not an 8 am one.
