The starting point of the stage is north of the historic main square of Windischgarsten in the Hauptstraße. Between the Grassecker bakery and the Kemmetmüller Hotel, a small lane runs north between the houses. At the end turn left and just after the bridge turn left again into Ufergasse. You will now reach the main road again. After a few metres, keep straight on into Salzastraße, which you now drive slightly uphill - always following the largest street - out of the village. Leave Villa Sonnwend on your left (or turn into the route here if you have stayed overnight at Villa Sonnwend). At the next crossroads, take the right-hand road towards Ruhrbauer. This road leads uphill and soon becomes a forest road, which is beautifully situated along a stream. The forest road soon becomes a narrower cart track and later briefly a meadow path, which now takes you alternately uphill and downhill to an asphalt road. The road takes you to some houses, which you drive around on the right - this is how you reach the crossroads with the many signposts that you already passed at the end of the last stage. You turn left into the uphill road that you descended on the last stage and ride the previous day's route in the opposite direction - past a car park and later on a forest road - up to the start of the Haslersgatter car park.
At the three forks in the forest roads, take the right-hand uphill road, which, after the short uphill passage, takes you mostly slightly downhill along the beautiful ridge (or just to the left of it) until you reach another forest road. Follow it slightly uphill to the Hanslalm and from there always downhill past the beautifully situated Kreuzau to the Zickerreith Hütte (refreshment stop) on the Hengstpass road. From there, take the road on the left uphill to the Hengstpass and then descend for about 10 km to Unterlaussa with the village of Dörfl.
You drive through the village and then turn right at the end over a bridge into a small, slightly uphill asphalt road. The road becomes a forest road, which you follow - always following the signposts - uphill to the Teufelskanzel (a vantage point over the valley) and further to a nameless saddle. From the saddle, simply descend the forest road - you can branch off once to the left onto a parallel wide forest path that soon joins the forest road again - until you reach a small asphalt road. Take the right-hand downhill road and follow it through the valley down to the Spitzenbachgraben. Here you turn left onto the road and soon right again onto an uphill road. Follow this road over a last small hill and down the other side to the main road of St. Gallen. Turn left here and ride across the main square to the finish of the stage in front of the municipal office on the other side of the square.
