19 JULY 2025
A great summer trail in the Vosges
On 19 July, Le Markstein will be the Vosges trail capital for a day. It's an opportunity to discover the massif in the sunshine and enjoy a km/climb ratio that's reminiscent of the Alps!
The longest distance will take you within a stone's throw of these two giants of the Vosges.
July can be a very changeable month in the mountains, and the Vosges is no exception to the rule. You could very well experience 30 degrees in the valley and approach 5 degrees on the summits.

COURSES
19 JULY 2025
In 2025, we have completely modified our routes. However, we would ask you to calculate a margin of 5 to 8% as we are still awaiting the necessary feedback and authorisations from the ONF and the relevant authorities. Thank you in advance for your understanding. As soon as we have received all the approvals, we will publish all the details here on the site.
