The climb from St-Jean-de-Sixt to les Confins
is not really difficult with only 508 elevation meters.
The first three kilometers from St-Jean to La Clusaz are even easy (2-4%).
After this winter sports resort, the road becomes a little steeper (6-7%)
and two kilometers further on,
just before the first hairpin turn,
the hardest part of the ascent begins.
Here the steepest kilometer of the trip (10.3%) is found.
After that, the remaining more than two kilometers are not really hard (4-8%).
Unfortunately there are buildings along the street almost everywhere.
In addition, the road is quite busy
so the tour is not the most scenic one.
However, after Clusaz there is a beautiful view of the Chaîne des Aravis.
The climb can be extended with the ride from Thônes to St-Jean-de-Sixt. That adds another 164 climb effort points (cep) and 332 elevation meters. Unfortunately, this extension takes place on a road with a lot of fast driving traffic in an unimpressive landscape.
