Allschwiler Klausenlauf: Course, Elevation & Route Profile

Course & Elevation

Start and finish sit at the Schulhaus Gartenhof on the southern edge of Allschwil. The first good half kilometre runs flat through the neighbourhood, then at kilometre 0.6 the first climb begins: 850 metres at a good six per cent on average with pitches over ten, lifting the course out of the village towards the forest. After a short recovery the second, longer climb starts at kilometre 2.9, 1.2 kilometres and around 55 metres of height to the high point at roughly 400 metres, in the woodland between Rittersmatt and Roemisloch close to the French border.

The second half is the same story in reverse. From kilometre 4.4 the route runs almost continuously back north and downhill, with the odd counter-rise, until the last kilometre and a half drop into the village and back to the school. In net terms the loop balances out, 158 metres up and the same again down.

2026 is the 47th edition, held on St Nicholas Day itself under the motto Schnälli Sogge and run by the Verein Klausenlauf with the Velo Club and Volleyball Club Allschwil, the Montibeux Club Basel and the Guggenmusik KanniBâle. The Hauptlauf is the last race of the day, men off at 13:45 and women at 13:50. It is the only race with a drinks station on course, at kilometre 5.2. Alongside the age categories there are awards for the fastest woman and man from Allschwil and for the FIRMACTIV company teams, after which the Renntier-Beiz opens.

Pacing Strategy

This loop punishes a fast start harder than most 10 km races. The opening 600 metres are flat and run in a packed field, and the steepest section of the day comes immediately afterwards. Run the flat introduction deliberately at target race pace and accept fifteen to twenty seconds a kilometre on the first climb rather than trying to hold the number.

The race is decided on the second climb between kilometres 2.9 and 4.1. It is shallower than the first but more than twice as long, and it arrives once the first climb is already in the legs. Run it evenly and six mostly downhill kilometres are left to take time back; blow up here and you lose it a second time on the descent.

The second half is a downhill race on tired legs, and that is the trap. A third of the course is on natural paths, which in December means wet leaves, soft ground and possibly frost in the forest, so the descent cannot be run as freely as the profile suggests. The drinks station at 5.2 km sits exactly where the climbing turns into the long descent, a good place to reset the rhythm deliberately instead of letting it go.

Training plan for Allschwiler Klausenlauf: 12-week build

For a well trained age-group runner the Hauptlauf takes roughly 40 to 60 minutes; the course records stand at 31:03 and 35:26. The demand is anything but even: almost half the loop climbs, a good third descends, and only about a quarter is genuinely flat. That produces a variable effort with two clear peaks rather than a held pace.

What decides the race are the two climbs in the first half and the ability to pick the pace up again immediately afterwards. Train it as hill intervals with an active continuation: four to six repetitions of three to four minutes on a five to seven per cent gradient, but each carried on for two minutes at race pace over the crest instead of stopping at the top.

The second emphasis is downhill running under fatigue, because from kilometre 4.4 the time has to be won on the descent. Put longer descents at the end of a steady run twice a week and run them deliberately with a high cadence and short ground contact; that protects the quadriceps more than any extra hill session.

Among the conditions, surface and season count. A good third of the course is natural path, run in early December in the early afternoon, so on cold, often damp ground with leaves in the forest. Do part of your volume in the woods rather than only on asphalt, race in a shoe with tread that you have already run on wet forest path, and plan a longer warm-up, because the first climb arrives after ten minutes.
