A 4-day trail course to prepare at best the legendary TDS ® race with logistics included for more comfort. Besides, the bags transport is provided every day and you can enjoy the magical Italy and Beaufortain landscapes and follow your guide’s advices!

Technical, wild and contrasted, you will progress on a route off the beaten tracks. You will be able to spot the traces, to prepare your race or just discover splendid landscapes on the course. A 4-day trail to run, explore, exchange, recognize a mythical journey and progress.

In the ‘extra’ section below, you’ll find information about the required trail running level you need to have. You will also see the equipment that you need to bring with you.

During these 4 days we will run on average 20-35km a day and go up from 1000 to 2000 meters. We will mainly be on single tracks and technical terrain. We will partially be on aerial paths.

Highlights of this 4 days of trail course are the following:
