This is actually a fairly easy ascent
but this is not true for someone
who is already really tired at the foot of the climb,
like me in 2015.
The ride can be divided into two sections.
For the first nine kilometers
the more or less straight road
heads northward through the valley of the Malsanne
and has a small gradient (mostly 3%).
Then a gradual transition takes place
to somewhat more serious climbing in the last three or four kilometers,
which run up to the pass in some big zigzags.
This part looks less steep than it really is
because the open landscape offers little reference.
Meanwhile, the slope secretly reaches 7 to 8%.
