The Jura Crest Trail (GTJ / GR509)

The Grande Traversée du Jura (GTJ / GR509) is a premier 400km long-distance trail snaking through the gentle, forested mountains along the French-Swiss border. Unlike the high-alpine peaks of the Alps, the Jura is characterized by vast limestone plateaus, dense spruce forests, and rolling sub-alpine meadows. The route is a contemplative journey through a 'Nordic' landscape, offering silence, deep isolation, and breathtaking views over Lake Geneva to the Mont Blanc massif. It is an accessible yet physically demanding thru-hike that showcases a unique mountain culture defined by isolated dairy farms and ancient spruce woods.

The Yorkshire Three Peaks is one of Britain’s quintessential endurance challenges. Walkers attempt to scale the peaks of Pen-y-ghent (694m), Whernside (736m), and Ingleborough (723m) in a continuous 38.6km (24-mile) loop, traditionally within 12 hours. Set against the stunning limestone scenery of the Yorkshire Dales National Park, the route takes you over vast moorlands, past the iconic Ribblehead Viaduct, and through charming stone villages like Horton-in-Ribblesdale. It is a severe test of physical stamina and mental fortitude, but the camaraderie on the trail and the beauty of the Dales make it an unforgettable achievement.
