The climb to the Signal de Bisanne is tough.
Above all, the road is steep
with an almost constantly increasing slope in the direction of the top
but also the number of elevation meters (1236) is considerable.
The ride begins near Villard-sur-Doron,
at a junction of the road from Beaufort to Albertville (D925).
From there, the quiet road winds itself,
with a total of 13 hairpin bends, up
towards the summit of Mont Bisanne.
The first six kilometers are not that steep (mostly 6-8%)
but after a hairpin bend to the left the effort increases (8-9%).
Four kilometers further, after a total of 800 elevation meters,
the road passes by the ski resort of Bisanne 1500.
Here the slope increases again.
On the next two kilometers the slope is constant at 10%.
As if that were not enough,
the hardest part follows after a bifurcation.
Here a narrow road to the left leads further up.
The remaining profile intervals of five hundred meters
have an inclination of 11, 10, 11 and 10%
but in fact cycling is more demanding than these numbers suggest
because short sections are even steeper.
Almost at the summit, the road branches again.
Turn right to get to the top.
