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

Ah, the Montaigne hill, when it's at the end of the course it can hurt, but it also tells us that we're almost there.

Ideal for a coffee break. There's a bar and a pastry shop that makes delicious macarons! There's a water fountain next to the church, a little further on.

The parish of Pecqueuse is part of a whole called "The Pastoral Sector of Limours", a sector divided into three groups. Pecqueuse depends in particular on the Limours group. The Saint Médart church is open every first Saturday of the month at 6 p.m. in winter, 6:30 p.m. in summer for Sunday mass. It has existed, probably in wood since the 11th century. The current church, with a single nave, was built in several stages; the choir being the oldest part, probably from the 13th century, local style vaulted in a cul-de-four then enlarged at the end of the 15th century. The altar and the altarpiece date from the 18th century, the woodwork of the choir in gray and gold perhaps comes from the grand seminary of Versailles. The altar painted in faux marble is decorated with an imposing tabernacle, also painted in gray and gold.
