  • New 2016 topoguide

The new issue of our GTJ biking route topoguide has been available since the summer of 2016. The route has been improved with new sections that will let you discover the richness of the area’s heritage.



The route is marked by enamel signs featuring GTJ symbols and installed on road signs. In the Jura and Ain departments, the route is marked in its entirety, while in the Doubs it is not yet marked, so we advise you to take the topoguide along.

3Guides, maps and GPS

Before venturing on the Grande Traversée du Jura’s biking route, we recommend that you take the “La GTJ à vélo” topoguide. This guide contains all the practical information that will enable you to prepare for your hike.

This topoguide can be purchased in our online shop.

If you have a GPS, you can download the route free of charge from this link:

4Difficulty level

The route is designed to please and allow visitors to discover a wide range of territories. The aim is not to collect as many ascensions as possible. There are a few difficult sections, so if you think they’re beyond your capabilities, you can take the alternative options described in the “La GTJ à Vélo” topoguide. We want to offer something for everyone, though, so if you like challenges, other options will lead you across some of our mythical passes: Grand Colombier, Faucille, and even a round-trip to the Mont d’Or summit.

5Individual equipment

Just like for long-distance hiking, you must be equipped to face different weather conditions and have the necessary tools to perform minor repairs. It goes without saying that your bike should be in a good condition and you should have tested it beforehand. Having the right tools for minor repairs is good, but knowing how to use them is better! If you have any doubts, contact an experienced rider to learn how to use a spoke wrench or a chain rivet extractor. Otherwise, you can also visit a bike repair shop on the way; they will know what to do.

When riding a bicycle, the position of your body makes carrying a backpack uncomfortable. The solution people most frequently adopt is to carry luggage on their bicycles (don’t worry, you will still get a good workout). Without going into technical details, we can suggest a rack with panniers at the rear, plus a pannier on top of the front wheel; this set-up is often seen on our routes. Another solution is to haul a trailer containing your luggage and/or housing your children and/or dog and/or… Let’s end the list here… There are advantages and disadvantages for each solution: panniers are great for  compartmentalising your luggage, a trailer is great because of the space it provides, … opting for a smaller volume versus a larger volume is a personal choice (remember: the more space you have, the more you will be tempted to take along, and the heavier it will get!).

It’s up to you to ponder these material aspects, as it all depends on what you already have, what you prefer, what your budget is, and so on…
