Today, we are joined by Rebecca Dent, an expert in Nutrition for Runners. Whether we have a race coming up, a new training plan, or simply want to improve our performance, Rebecca will provide clear, practical advice on fueling for trail running. We’ll cover key topics such as common nutrition mistakes, hydration strategies, sweat rates, sodium needs, and the balance between real foods and sports products. This is a great opportunity to learn how to optimize our nutrition for both training and race day.
Our run begins with a scenic train ride towards the Swiss-French border on the Mont Blanc Express. We start at Montroc and follow the Chemin des Diligences. We’ll see cows producing milk for local cheese on alpine pastures. We gain elevation using lightweight running poles to reach Col des Possettes (1,997 m / 6,551 ft). After a coffee stop, we continue to Aiguillette des Possettes (2,201 m / 7,221 ft), where we enjoy panoramic views and a high-altitude picnic. From here, we have a fun descent down to the valley floor and the village of Le Tour. There is an optional cable car descent for those who want to shorten the run.
