Belle montee, helas a la limite de mes capacites [56ans et quand meme en bonne forme]. Malgre une pause a mi cote, j'ai mis 5minutes a m'en remettre arrive en haut. C'est court mais c'est intense. Les lacets sont superbes et permettent de reduire un peu la pente, mais il faut etre costaud.

De loin la côte la plus dure de loire-atlantique, ces petits lacets sont totalement uniques dans la région.
Attention au braquet si vous voulez garder une cadence correcte car j'étais totalement à l'arrêt sur mon 36:25, ça monte autant que le mur de Saint Fiacre, mais c'est 3 fois plus long !

The best and most difficult climb around Nantes. 350m at 20% non stop. It's violent, it stings hard.
The subtlety here is the mini yaw that you can actually cut through the inside of the bends. Indeed on the inside of the bends the climb is a constant 20%+ wall for 300m so expect to be rubbing the 30%. However if you go through the outside at every turn then the climb is 50m longer and you will be between 15/20%. It seems almost rolling, but watch out for the last ramp to call you to order.
To be done in Nantes. If you continue for 1km before going back down to Oudon you will also have one of the most beautiful views of the Loire valley.

La meilleure et surtout la plus dure ascension autour de Nantes. 350m a 20% non stop. C'est violent ça pique fort.
La subtilité ici c'est les mini lacet que vous pouvez en fait couper par l'intérieur des virage. En effet a l'intérieur des virage l'ascension est un mur a 20%+ constant pendant 300m attendez vous même a frolez les 30%. Cependant si vous passez par l'extérieur a chaque virage alors la l'ascension est 50m plus longue et vous serez entre 15/20%. Ça paraît presque roulant, mais attention a l'enflamade la dernière rampe vous rappellera a l'ordre.
A faire sur Nantes. En poursuivant votre route sur 1km avant de redescendre vers Oudon vous aurez aussi l'une des plus belle vue du coin sur la vallée de la Loire
