Erfurt Triathlon: Course, Route Profile & Map

Course & Elevation

The day starts on the broad sand beach of the Strandbad Stotternheim, from which the field runs into the Stotternheimer See. The 1,500 metres are swum on a buoy course in the lake, and it is only a few metres from the exit into the transition area.

The bike course leaves the Strandbad towards Schwerborn and turns right at the K53 junction onto the Schwerborner Straße towards Erfurt, where a turnaround sits just before the town limit. The return runs back through Schwerborn and the Ilversgehofener Straße. One lap is ten kilometres and the Olympic distance rides four of them, covering the access leg out to the K53 junction only once. The elevation band stays between 171 and 188 metres, four fifths of the course is flat, and the course analysis finds no rise that deserves the name. The access leg runs on a concrete slab road whose bumps are marked; a full road closure is aimed for.

The run uses the cycle path beside the road Zum Stotternheimer See towards the landfill and Schwerborn, an out-and-back covered as two five-kilometre laps. The profile is tame here too: the path climbs just under 18 metres between kilometre one and two and a half, drops back by kilometre four and is otherwise flat. Over ten kilometres that comes to around 38 metres. The finish is inside the Strandbad.

Pacing Strategy

On a course without climbs everything shifts onto consistency. Swim the 1,500 metres under control and without a starting sprint, because an overcooked opening on the buoy course costs you more on the bike than it ever returns.

The bike leg is effectively a 40-kilometre time trial: set a target power for the flat sections and hold it in the aero position instead of letting the lap structure tempt you into surging. The race is decided at the turnarounds just before Erfurt and back in Stotternheim; each one bleeds speed you then have to rebuild without jumping out of your power window. Four laps mean eight of those re-accelerations.

The trap waits on the run. After 40 flat kilometres, the gentle rise on the first run lap feels harder than it is, and running it to feel rather than to the watch costs you the second lap. Hold the first lap deliberately a shade under target race pace and use the descent after the turnaround to lift.

Training plan for Erfurt Triathlon: 12-week build

For the Olympic distance in Stotternheim, expect roughly two and a quarter to three hours of racing depending on your level. The effort is steadily aerobic for long stretches and sits just under threshold on the bike; there are no climbs to push you briefly above it and no descents to recover on.

That is exactly what defines the demand: one long, uninterrupted stretch of pace toughness rather than an interplay of efforts. Train only intervals and you arrive with no feel for what 60 to 75 minutes of constant race-pace work in the aero position actually costs.

The race is decided at the eight bike turnarounds and in the first kilometre and a half after transition. That is where you find out whether your power curve stays flat and whether the legs can find race pace immediately after 40 kilometres.

So build around long threshold blocks of 15 to 25 minutes in race and aero position, with re-accelerations from low speed folded in to rehearse the turnarounds. For the run, brick sessions off exactly that kind of steady ride are the core, plus tempo runs at your target ten-kilometre pace on flat ground. Open-water practice with buoy sighting and a standing beach start round out the preparation.
