The snail's hill: training at Marcoussis is climbed seated, developing 44x19 or 42x18. The secret is to spin.

Typical Île-de-France coastline. Approximately 1km at an average gradient of 5-6%. It climbs to 7-8% on the last bend before reaching the village of Magny. Often used to get to the Chevreuse Valley from Paris/Versailles. There are a few cars, but the road is wide enough for overtaking.

a fairly pleasant hill. You can turn around at the traffic lights at the top, go back down and take the cave towards Gif

"God loves every soul with an undying love. He approaches each one with repeated, unspeakably patient offers of redemption. Even a small sign of love is enough for him to forgive and redeem. Our dear departed ones lacked a life preserver for the body; but the spiritual life preserver was not lacking, the breath of God in which the soul can clothe itself in a tiny moment, much more quickly than the body could." (Text by Albino Luciani / Pope John Paul I)

Every village was affected by the two world wars. If there were another war, I wonder if there would be as many young people mobilized in all these villages!
