Südkärntner Triathlon: Course, Elevation & Route Profile

Course & Elevation

The start goes at 10 am from the Strandbad Bellevue: 1,900 metres on a counter-clockwise triangle course, starting and finishing on the same beach. The cut-off is one hour for the swim, five hours for swim and bike together and eight hours for the whole race.

The bike course covers a 22.4 kilometre circuit four times, from Sankt Kanzian via Unterburg, Eberndorf, Gösselsdorf, Sittersdorf, Rückersdorf and Sankt Primus, past the Turnersee and back. The organiser gives 190 metres of climbing per lap, so 760 in total. Around 36 per cent of the route is level and a good three per cent sits in the steep uphill band, concentrated above all in one place: the Mochoritsch hill at kilometre 15.5, which the organiser itself calls the Heartbreak Hill. Roughly 750 metres at nearly nine per cent average with a peak above 20, ridden at kilometres 15, 37.5, 60 and 82.5. Drafting is prohibited.

The run is four laps of the 5.3 kilometre circuit around the Klopeiner See: along the east shore, up the south shore to the viewing platform at kilometre 1.2, through Klopein and back along the north-shore promenade. At 43 metres of climbing per lap the course is not flat but it is even: 39 per cent of it falls gently, 32 per cent rises gently and only a quarter is genuinely level.

Pacing Strategy

Swim the 1,900 metres clearly below the intensity that feels right on a triangle course. Over a total of five to seven hours the swim decides nothing, but it costs everything if it is raced too hard.

The race is decided on the Heartbreak Hill in its third and fourth repetitions, at bike kilometre 60 and 82.5. A 750 metre ramp at nearly nine per cent is not a mountain inside a half distance, it is a power-spike generator: four such climbs above threshold cost more carbohydrate than the remaining 86 flat kilometres together. Ride them in the easiest sensible gear, seated, and accept the low speed.

The main trap is the lap structure of the run. Four laps mean passing the same viewing platform, the same spectators and the same clock four times, and the gently undulating course offers no section in which a collapse could hide. Run the first lap deliberately ten to fifteen seconds per kilometre slower than target race pace. Then the conditions: a 10 am start in mid-September puts bike and run into the warmest part of the day, and the north-shore promenade lies open beside the water. What you take in on the bike decides what the last two run laps look like.

Training plan for Südkärntner Triathlon: 12-week build

The half distance at the Klopeiner See takes an age-group athlete roughly five to seven hours; the cut-off is eight. The demand is a long, largely steady aerobic effort broken by four short and distinctly supra-threshold climbs on the bike.

That mixture is what makes the preparation specific. Ride only long steady sessions and you will have nothing in reserve for the Heartbreak Hill; ride only intervals and you will not have rehearsed the position or the nutrition for the 86 flat kilometres around it. Both have to come together.

The training emphasis therefore belongs on long rides of three to four hours containing 4 times 3 to 4 minutes on a climb of eight to ten per cent, embedded in race-pace sections in the aero position. After each ramp the point is to be back at target output within two minutes, exactly what the course asks four times.

For the run, brick sessions of 30 to 45 minutes straight off those rides are the core work, run on gently undulating ground rather than a track. Add a race nutrition plan rehearsed across hours with a fixed carbohydrate intake, heat adaptation for a midday run in September, and open-water work on a triangle course sighting anticlockwise.
