The Vëlosummer Challenge is open to everyone!

You don’t need to be a tech expert—everything you need to know about using the VisitLuxembourg app is explained below. 

👉 Please note: An internet connection is required to use the VisitLuxembourg app.

The challenge is simple and fun:

There are 14 check-in points, each located along a different Vëlosummer tour. At each point, you’ll answer one quiz question using the VisitLuxembourg app. 

Here’s how to get started: 

• Download the VisitLuxembourg app (or update it to the latest version). 
• Open the app, go to the Challenges section, and select the Vëlosummer 2026 Challenge. 
• As you approach a check-in point, stop, open the app, and check in. 
• Answer the quiz question linked to that location. 
• Repeat this at all 14 check-in points. 

Once you’ve completed all check-ins, you’ve earned your Vëlosummer yellow jersey—congratulations! 

There is one check-in point per Vëlosummer tour, making a total of 14 check-in points.
Before you start your ride, you can check the exact locations through the following sources to make sure you don’t miss any: 

• In the VisitLuxembourg app: Open the challenge to see all check-in points. 
• On the printed Vëlosummer map 
• On Geoportail: https://g-o.lu/3/7kvqM 
• On the tour itself: Each check-in point is marked with the official Vëlosummer Challenge symbol. 

There are 14 check-in points in total, each linked to a quiz question.
Even if a tour offers multiple route options—like VëloViaNorden with its H1 and H2 variants—there will still be only one check-in point for that tour. 

Yes, you’ll need the VisitLuxembourg app to take part in the Vëlosummer Challenge.
You can download the app here. 

To get started:

1. Open the app and take the onboarding tour—it will guide you through how the challenge works. 
2. Create a username and enter your email address. These are required so we can contact you if you win. 

To ensure the Vëlosummer Challenge works seamlessly in the VisitLuxembourg app, please check the following before you start: 

• Update the VisitLuxembourg app to the latest version 
• Update your phone’s operating system to the most recent version 
• Enable location services and set them to “always on” 
• Turn off battery-saving or low-power mode to avoid interruptions 
• Complete the onboarding tour in the app (you’ll find it under the introduction text of “Challenges”) to understand how the challenge works. 

If you need to reset your phone or reinstall the VisitLuxembourg app, please note that any points you've earned within the app will unfortunately be lost. However, your points will still count toward your final score in the challenge.

If this happens, please contact us at velosummer@eco.etat.lu and include both your old and new usernames, as well as the email address(es) you used to register.

If the challenge doesn’t appear in the VisitLuxembourg app, try the following:

• Make sure you have an active internet connection
• Update the VisitLuxembourg app to the latest version
• Update your phone’s operating system to the most recent version
• Enable location services for the app
• Check the correct section in the app (Challenges)
• Restart the app
• In some cases, reinstalling the app can help

If you experience any technical problems during the challenge, follow these steps: 

• Read through this FAQ section to see if your issue is already addressed. 
• Check for updates: Make sure both your phone’s operating system and the VisitLuxembourg app are up to date. 
• Take the onboarding tour in the app (found under “Challenges”) to ensure you understand how the challenge works. 
• If the issue persists, contact us at: velosummer@eco.etat.lu
• If you're already on the tour and encounter a problem at a check-in point, take a screenshot of your map or a photo of the location. This helps us verify that you were in the right place. 

Common technical issues and how to fix them  

• Check-in point not appearing: Make sure location services are set to “always on” and that you’re physically near the check-in point. Try restarting the app. 
• App not responding or crashing: Close and reopen the app. If the issue persists, reinstall the app and ensure your OS is up to date. 
• Quiz question not loading: Check your internet connection. If you're offline, move to an area with better signal and try again. 
• Battery-saving mode interfering: Turn off any battery-saving or low-power modes, as they may restrict GPS or background activity. 
• Can’t submit answer: Ensure you have a stable internet connection. If the issue continues, take a screenshot and send it to support.
• If your score is not displayed correctly, but you were able to answer the quiz normally, this is usually due to a delayed synchronisation, which will take place no later than the end of Vëlosummer.
• For phones running on the Android operating system: if you do not receive a notification at a tourist attraction, this may be due to a limitation of the Android operating system, which can cause location detection to take up to 6 minutes. In this case, please open the app yourself to access the check-in. If the check-in still does not work at the location, please close the app completely. Depending on your device model, tap the button for recently used apps (the three lines next to the Home button) and close the app there, or press and hold the Home button and close the app by swiping it upwards or to the right. Then open the app again. Your location will be detected again, and the check-in should work.

Challenge period:
The challenge runs from 18 July to 16 August 2026 and is only accessible during these dates. 

Check-in points:

• Each check-in point is only active during the Vëlosummer period.
• For safety reasons, we strongly recommend completing the tours during the official road closure dates.
• For example, the Uewersauer-Tour is scheduled for 18 and 19 July 2026, and roads will only be closed on those dates. 

After Vëlosummer 2026 ends, we’ll get in touch with you—most likely towards the end of August, to confirm your jersey size. 

The yellow jerseys will be produced and made available a few months later. We’ll keep you updated by email! 

Nope! The yellow Vëlosummer 2026 jersey will feature a brand-new design, giving it a fresh look that celebrates this year’s edition. An award ceremony will likely take place in late autumn.

It’s a unique reward just for 2026 participants!
