Each runner must bring their own helmet (e.g., a bicycle helmet), a headlamp (cell phones are not allowed), and a sweater. During the last 3 kilometers through the mine, the maximum temperature is 10°C! If the outside temperature is high, the difference with the mine is extreme. Therefore, we recommend wearing a sweater to avoid thermal shock.

Your helmet, headlamp, and sweater must be left at the checkout when you pick up your race bib. Our team will pack everything into a bag and leave it, along with your race number, at the mine entrance. A transition area is set up in front of the mine where you can collect your belongings.

Wearing a helmet and using a headlamp are mandatory in the mine. Failure to comply will result in disqualification from the race!

We provide 3 aid stations along the 14-kilometer race course and 3 aid stations along the 20-kilometer race course. In addition, a refreshment station is planned at the finish line.

The awards ceremony takes place near the information point at the National Iron Mining Museum. The Rumelange aperitif also takes place there, with food and drinks stalls and live music.

Changing rooms and showers (separate areas for men and women) are available to runners at the "Will Hoffmann" sports hall in Rumelange. After the race, a shuttle will run continuously between the finish area and the sports hall.

The results will be available on our website www.tdm.lu the day after the race.
