Please note, I started this loop, after 15 km (starting from Camiers and stopping at Pont de Briques), I changed because it was only road, I do not recommend it for mountain biking.

The Église Saint-Wulmer is a church in Parenty, a commune in the Pas-de-Calais department in the Hauts-de-France region of northern France. The church is located on Rue De L'église in Parenty. The church is dedicated to Saint-Wulmer, a monk of Haumont Abbey in Hainaut3. The parish is confirmed in 1190 by a papal bull confirming the tithe of Parenty to the canons of Thérouanne. The church consists of a nave and an older choir, separated by a central tower. The arms of Jean de Blosset, baron of Doudeauville, who held the seigneury from 1513 to 1536, allow us to date the choir vault to the first third of the 16th century4. The tower bears the year of construction “1614”, but the first level was only vaulted in 1642. It shows elements of defense, including the remains of a bretèche above the gate. The nave was built several years after the tower, as evidenced by a date engraved in the ceiling.
