FATMAP difficulty grade
Starting in Lienz, the first 20km are flat along the B100 to Oberdrauburg.
It is there that the first climb of the day begins onto the Gailbergsattel at 981 metres above sea level.
With a steady gradient of no more than 10%, the well-maintained road winds its way up into the mountains via ten switchback corners.
With the first 350 vertical metres of the day completed, it is time for the 5km descent down to Kötschach.
Here it is worth pulling on the brakes every now and then and stopping to enjoy the great views.
Kötschach-Mauthen is on the border between Tirol and the neighbouring province of Carinthia, giving riders access to the pretty Lesachtal Valley. Down in Kötschach-Mauthen it is time to take a deep breath and get ready for the 37km climb up to the Kartitscher Sattel along the Karnische Dolomitenstraße.
It is hard to get into any kind of rhythmn on this road because it continually switches between climbs and short descents (19 in total), meaning that as well as the 820 vertical metres between top and bottom riders also have to climb a further 420 vertical metres which they lose through these descents.
Highlights along the way are the Maria Luggau church of pilgrimage and the beautiful village of Obertilliach.
The views south towards the snow-covered mountains are particularly impressive in autumn and spring. Once riders have reached the top of the climb at 1,530m they can look forward to a fast descent via numerous switchback corners to the village of Tassenbach in the Pustertal Valley.
Instead of taking the Drau Cycle Path (to the right), riders cross the river and follow the Drautal Bundesstraße main road to Abfaltersbach.
Here riders leave the B100 and turn off onto the Pustertaler Höhenstraße road towards Anras.
This is where the final climb of the day begins - 29.5km and 845 vertical metres.
This section of the ride has been used twice by the organisers of the Giro d’Italia (1994 and 2007) and has punishing gradients of up to 17%. With the day's climbing done, it is time to enjoy the flat final section winding its way along the south-facing side of the Hochpustertal Valley through many pretty villages all the way down via Bannberg to Leisach.
From here it is just a question of completing the final few kilometres along the B100 back to the starting point in Lienz. Tip! We recommend starting this ride as early as possible.
Due to the large amount of climbing involved this ride should not be underestimated.
The first climb onto the Gailbergsattel can also be quite busy with traffic later in the day. Source: https://www.tyrol.com/things-to-do/sports/cycling/biketours/a-gailbergsattel
