News: Pierre’s peaks

Pierre's grand expeditions

CWW’s favourite Frenchman has brought the spirit of Alpine adventure to Chilterns walking.

Pierre Roche says his Grand Huit, Grand Neuf and Grand Dix walks pack in the maximum possible ascent, providing the perfect formula for those who like to test themselves on a bracing hike:

The walk distances are 19km (12 miles), 21km (13 miles) and 23km (14 miles).  They include 8, 9 and 10 hills, providing 640 metres, 740 metres and 820 metres of ascent with the added challenge of completing the walks within a set time.

In July 2025 Carol, Linda, Caroline and Pierre completed the Grand Dix in a record-breaking 5 hours and 31 minutes.

As a rule of thumb, the undulating landscape of the Chilterns offers walkers one hill every mile, each with about 80 metres of ascent. Turville Hill provides the pinnacle climb of the series with its famous landmark, the Cobstone Windmill.
