SEEN-LAUF Tannheimer Tal: Course, Elevation & Route Profile

Course & Elevation

The 25 km run is the long running course of the SEEN-LAUF Tannheimer Tal, a single loop through the high valley around Nesselwängle in the Austrian Tyrol. The lakes that give the event its name and the surrounding peaks frame the route; the profile itself is rolling rather than alpine, with roughly 370 metres of climbing spread over the full distance.

None of the climbs is long. After a short rise right off the start line, four waves follow at kilometres 10.8, 16.7, 20.9 and 23.7, each between 400 and 800 metres at three to five percent average gradient. The steepest moment comes on that final rise just before the finish, briefly touching nine percent. About a quarter of the route is flat and the rest rolls gently, with virtually no steep ground in either direction.

The SEEN-LAUF is a summer running festival organised jointly by four local clubs, with formats ranging from kids' races to a 25 km trail. The most recent edition sold out at around 1,800 participants across all distances. The 25 km is the longest running race of the day and pairs an honest, fast profile with the scenery of the Tannheim valley.

Pacing Strategy

The 25 km Run lives on even pace. Over 60 percent of the course rises or falls only gently and a good quarter is flat, so steep pitches that force you to walk are entirely absent. That means you can and must find a rhythm here and hold it. The small climbs at kilometres eleven, seventeen and twenty-one are moderate at under five percent, but at the end of a long run they decide whether you hold pace or fade, so run them economically rather than attacking them.

The biggest trap is starting too fast on the flat opening; at a good 1,100 metres of altitude the body forgives a fast start less than at sea level. Distribute your effort evenly, keep your turnover up on the rollers, and save a little reserve for the last five kilometres, which are gently undulating.

Training plan for SEEN-LAUF Tannheimer Tal: 12-week build

Plan on roughly two to two and three-quarter hours for the 25 km with its 370 metres of climbing, depending on your level. The effort is steadily aerobic: there are no long climbs and no technical ground, but the constant gentle rolling keeps interrupting your rhythm in small ways.

The race is decided in the second half rather than at any single point. The rises at kilometres 16.7, 20.9 and especially 23.7 arrive on tired legs; running them controlled instead of forcing the pace costs almost nothing and leaves room to push again on the flat sections in between.

In training that translates to a solid base of long runs, ideally over rolling terrain, so your body learns to absorb frequent small changes of rhythm at an even effort. Add threshold work of 20 to 40 minutes to carry your race pace across the distance. Hilly fartlek sessions or steady runs with short climbs built in mirror the course better than flat track intervals.

Practise settling straight back into pace after a short rise, because that is exactly what the finale asks of you when the steepest ramp of the day only appears at kilometre 23.7. An even pacing strategy with a small reserve for the final five kilometres suits this course far better than a fast start.
