The Location
The Sure-to-Sure Swimrun race is organized just West of Esch-sur-Sûre, in the North-West of Luxembourg. This region is arguably one of the best locations for swimruns imaginable. The meandering arms of the Upper-Sûre reservoir lake and hills around it makes for ideal and safe swimming distances while the dense forests around Öewersauer Nature Park and the surrounding hills hold truly magnificent views. We fell in love with this beautiful place and decided to organize our own version of the popular endurance sport: The Sure-to-Sure Swimrun Luxembourg!
If you are looking for a place to stay in the area, there are several options:
-
Van der Valk Hotel Arlon (35min by car)
-
Youth Hostel Lultzhausen (located right at the start/finish)
-
Logis Gourmet & Relax Hotel (5 min by car)

-
Camping Fuussekaul (15min by car)

Hotel Saint Fiacre (20min by car)
The Race
24.4 Challenge
The 24.4 Challenge route: Around 24 kilometers of trail running and 4 kilometers of swimming, spread across 10 swim sections in the river Sure. Several replenishment points along the way provide much needed sugars & water and first-aid teams are ready and stand-by at all times. Please note that the organisation has the right to change the route to its sole discretion. Any amendment will be communicated before the race. The start of the race will be at 11:45 am. After the last contestant crosses the finishline we close the day with the award ceremony! Barbecue will be available throughout the course of the afternoon from 14:00 till 20:00.

10.3 Sprint
The 10.3 Sprint Route: As we received many requests for a second, shorter route we wanted to come up with a track that is easy enough for first-timers but is still challenging and takes you along some of the best trails and view points. We really think you will love the new and improved SPRINT route which will start at 12:00 noon!

The Rules
Participants start and finish the race as teams of two, running and swimming the whole course together, helping each other where possible in an effort to be stronger than the weakest link. A special feature of swimrun is that teams are allowed to carry anything they want (except floating devices or motorized items) as long as they finish with all their items. Teams have come up with a whole range of creative solutions, however the bungee cord connecting team members seems to be one of the more efficient ones on the swim which obviously induces a strong team spirit.
