Your Weekend Schedule

L’Hermine has crafted a flexible program so everyone can experience their adventure at their own pace. 2 base courses, 4 route options, but only one philosophy: friendliness!

🗺️ Your Route Options

To each their own track, to each their own style. Choose the package that suits you best:

Option 1: Bikepacking Mode (300 km or 400 km)

• The Concept: Perfect for getting into long-distance riding and testing your gear in real-world conditions.
• The Timing: Start on Saturday morning. You manage your overnight stay self-supported and have until late Sunday afternoon to complete the adventure.

Option 2: “All-Comfort” Discovery Mode (2 x 150 km or 2 x 200 km)

• The Concept: Two beautiful days of Gravel riding without the weight of loaded bags. On Saturday and Sunday, you ride a completely different loop.
• The Benefit: On Saturday night, you return to the comfort of your accommodation at the campsite for a recovery night before hitting the trails again the next day.

⏱️ Time Cut: No matter which distance you choose, the only thing that matters is getting back safely. You will have until late Sunday afternoon, 6 September, to cross the finish line.

🗓️ Weekend Highlights

Because the GTB Series is above all a human adventure, here are the key moments waiting for you at Camping de Pen Palud:

The Routes: Between Land, Rias, and Ocean

The Call of the Open Sea and Freedom

Southern Brittany like you’ve never seen it before. In September, the light shifts, the summer crowds fade away, and the Breton coastline reveals its wildest face. For this Autumn Edition, we have crafted a route that breathes ocean air, wide-open spaces, and pure freedom.

🗺️ The Playground: Between Morbihan and Finistère

Get ready for a unique visual journey. The route will take you on a conquest of the famous rias—those river valleys flooded by the ocean where turquoise water blends into the deep green of coastal forests.

• Terrain: A tasty mix of fast-rolling gravel tracks, forest paths, and tiny backroads forgotten by modern maps.
• Atmosphere: Secret passages between traditional stone thatched cottages, crossings of authentic fishing ports, and breathtaking panoramas over the Atlantic.
• Vibe: Imagine the sound of seagulls at sunrise, the scent of salt in the air, and that feeling of absolute freedom on your machine. Whether you are a distance junkie or a scenery lover, this route is designed to leave an impression on your mind, not to break your legs.

🚴‍♂️ Accessibility First: Gravel for Everyone

This is the absolute golden rule of the GTB Series! Unlike our classic ultra-distance events, we have deliberately avoided major technical difficulties and punishing elevation gains.

We want to offer you smooth, accessible routes to introduce you to long-distance riding with a smile.

• Want to travel light? Choose the 2-loop option (Saturday and Sunday). You get to enjoy the 300 km or 400 km courses without the hassle of carrying all your bikepacking and camping gear.
• Want to taste the full bikepacking adventure? The full 300 km and 400 km non-stop tracks are the perfect formats to test your self-sufficiency and overnight management.

🪵 Home-Cooked Routes Mapped with Love

Every route is scouted, tested, and approved by L’Hermine. And for good reason: you are riding on his very own home turf!

Living just 400 meters from the start line, L’Hermine knows every trail, every secret singletrack, and every forgotten backroad like the back of his hand. This local expertise guarantees an optimized, safe, and perfectly fluid route. And that makes all the difference!

🗺️ The final GPS tracks and the technical guide will be shared with you a few days before the event. For any logistical questions, don’t forget to check out the Participant Guide.
