The Val d'Aran in its purest form
Past and present. Earth and water.
The CDH, Camins d'Hèr (Iron Roads), is a journey through some of the wildest areas of the Val d'Aran. It means discovering the mining history of the valley, going through tunnels and mines at the foot of the imposing Mauberme, and immersing yourself in landscapes full of lakes, waterfalls and rivers.
Starting in the town of Les, the CDH is 110 kilometres and 6,400 metres of positive height gain during which tradition and nature come together in perfect harmony.

It is the responsibility of the runner to judge, according to these criteria, whether his jacket is adapted to the regulations and therefore to bad weather in the mountains.

At the race-pack collection, each participant receives two 30-liter bag. After filling it with the items of their choice and closing it, they can drop them in a place close to the starting line. One bag is taken by the organization to Beret and the other one to Arties. Upon arriving in those aid stations, runners will be able to collect the bag. When the runner leaves the aid station, the runner in person will have to deposit the bag in the area indicated for this purpose. The organization will return the bags to Vielha.
How to get your bags in Vielha: The bags are returned to either the runner or a family member or friend, only upon presentation of the race-bib. The bags must be retrieved no later than 2 hours after the end of the race. After that time, the runner must come, in person, to retrieve their bag at the organization headquarters in Vielha.
The organization will take to Vielha the bags of runners who drop out, on condition that their withdrawal is registered. Because of logistical factors, the organization cannot guarantee that all bags are brought to Vielha before the end of the race.
Only bags supplied by the organization will be transported. Poles are not allowed in these bags. As the items in the bags are neither checked nor controlled, we will accept no claims on that matter. We recommend not to put any valuable items in the bags. We advise you to keep toiletries and spare clothes in Vielha.
For logistics reasons, UTMB® World series events only accept the UTMB® World series spare bags that are distributed during the check-In. Those bags are reusable, so we ask the runners who already have received one of those bags to reuse it each time they take part in a UTMB® World Series event.
Pacers are not allowed to set the pace in the race.
