Trumer Triathlon.
The Mitteldistanz is the headline race of the Trumer Triathlon: 1.9 km in the Obertrumer See, three laps over the Haunsberg and a flat half marathon through the middle of Obertrum. The day falls into three very unequal parts, and the result comes out of the order they are raced in. The half marathon comes last, but it is handed out on the bike.
Trumer Triathlon 2027: Course, Elevation & Route Profile
The swim is held at the Strandbad Obertrum and splits into two unequal laps: 750 m along the red buoys first, then, after a short beach exit, 1,150 m along the yellow ones. The pro field goes off ahead, the age groupers follow in a rolling start from two corridors seeded by estimated swim time. Then comes the longest transition of the weekend, roughly 350 m of running from the swim exit to the transition zone in the village centre.
From there the bike leg heads out for three identical 29.5 km laps, each with the climb up the Haunsberg and a rolling return around the Obertrumer See, on roads open to traffic throughout. The half marathon then stays in town: four flat laps along the Mattig, through the grounds of the Trumer brewery and, every single time, straight across the finish area. Transition and finish share one site while the lake sits outside it, so the race moves from the water into the village once and never leaves again.
The Mitteldistanz closes a three-day festival that opens on Friday with the Seecrossing open-water swims and fills Saturday with the fun, sprint and kids races, all of it built around the Trumer Village. It is fenced in by a chain of cut-offs: for the swim, for starting and for finishing the last bike lap, and for the finish itself. Miss one and your day ends there, however good the legs happen to feel.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.

How to pace Trumer Triathlon.
Settle into the race
The time is distributed very unevenly. The swim is the shortest section, yet it can hold the most expensive mistake, because 350 m of running and the first Haunsberg climb follow immediately. The rolling start takes the pressure out of it: you swim against the clock rather than against the shoulder next to you, and you can race your own plan from the first metre.
Spread the effort
The Mitteldistanz is settled in two places, and both come late: on the third bike lap and on the third run lap. Everything before them is preparation for still having a choice once you get there.
Finish strong
The trap is T1. After the beach exit, the swim exit and the long run-in your heart rate is high, the bike is waiting and the climb starts at once. The first ten kilometres on the bike are therefore the single most important place to hold back all day. The second trap is the clock: the half marathon falls into the warmest hours, and whatever you did not drink on the bike cannot be recovered there.
Training plan for Trumer Triathlon: 12-week build
Build all three disciplines
Plan for roughly five to seven hours depending on your level, with the bike accounting for about half of it. The demand is aerobic and submaximal throughout, but never monotonous: a swim split in two by a beach exit, a hilly bike leg of three identical laps, a flat half marathon with no structure at all. The real requirement is not any one discipline but the ability to change the type of load twice without losing time or composure.
Brick sessions
The race is decided in the final third of each discipline: the third bike lap and the last seven kilometres of the run. Neither is prepared with isolated hard sessions but with long brick workouts in which the run starts after three hours on the bike, not after forty minutes.
Practise transitions
Conditions belong in the plan. Mid-July in the Salzburg lake district brings cool morning air over the water and real warmth from midday, often humid and prone to afternoon storms, and that lands precisely on the second half of the race. Heat exposure in the final weeks, a fuelling plan calculated across five to seven hours and a drinking routine rehearsed in training are performance factors here, not side issues.
Arrive fresh
Put your emphasis on what the combination asks for: open-water swimming with buoy sighting and a rehearsed exit, so the beach lap change is not a break in rhythm; three to four hundred metres of barefoot running, so the way into transition is not the first injury of the day; and full transition run-throughs at race pace, in both directions.
