To cover as many kilometres as possible by bike for both private and professional purposes in order to help protect the climate, promote cycling and improve the quality of life in municipalities – and ultimately have fun!

When does it happen?

TOUR du DUERF takes place every year from 10.- 30.09.

Who can participate?

Anyone who lives, works, belongs to a club or attends school / university in a participating municipality or region.

How can I participate?

  • Your municipality (i.e. town, municipality, region) first needs to register for TOUR du DUERF. The local coordinators are responsible for preparing and running the campaign – please contact them first should you have any questions.
  • Once your municipality has registered, you can sign up for the cyclist portal, then either join an existing team or form a new one. If you decide to form a new team, you will automatically be designated the team captain.
  • It is not possible to participate as a “teamless” cyclist – after all, climate protection and cycling promotion require teamwork! Teams of just two people are allowed though. Alternatively, each municipality has an “open” team that you are able to join. If you are the only active cyclist in a team when the seven-day grace period for entering kilometres after the campaign ends, you will automatically be moved to the municipality’s “open” team.
  • Everything classified as a bicycle in the Luxembourg "Code de la route" is permitted – this includes "pedelecs" with an engine output of up to 250 W.

How do I collect kilometres?

  • Enter every kilometre you cover by bike during the 21-day campaign period in your online cycling log – either directly via the TOUR du DUERF / CITY CYCLING app or by logging into the cyclist portal. If you do not have internet access, simply submit your kilometre log to your team captain at the end of each week. Cycling competitions as well as indoor training on stationary bikes are excluded here.
  • It does not matter where the kilometres were covered – after all, climate protection knows no city or state boundaries.
  • It is possible to record the kilometres cycled by multiple cyclists (e.g. entire families, school classes, etc.) in the same online cycling log. IMPORTANT: be sure to indicate the exact number of people for whom you are entering kilometres!
  • It is up to you to decide how detailed you want to your kilometre entries to be (each individual trip, a daily total or – at the very least – a grand total at the end of each week).
  • You can join or form a team up until the very last day of the 21-day campaign period. Kilometres can be entered retroactively as long as they were covered during the 21-day period.
  • There is a seven-day grace period after the campaign period ends for cyclists to finalise their kilometre logs. No new entries or changes are possible after this time!

Who wins at TOUR du DUERF?

  • The results of all participating municipalities and teams will be published on the website as well as on your municipality’s subpage.
  • Climate Alliance honours the most active local parliaments and municipalities within each of the five population groups (based on the number of inhabitants), along with the best newcomer municipalities in the three population groups with the most newcomer municipalities. On the local level, the participating municipalities are encouraged to also award prizes to the best local teams and/or cyclists.
  • See also rules in detail for the full rules of participation.
