The Vëlosummer 2025 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 2025 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: http://g-o.lu/3/4DAX  
• 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 G1 and G2 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 2025 Challenge.

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. 

Challenge period: 
The challenge runs from 19 July to 24 August 2025 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 Mamerdall Tour is scheduled for 19 and 20 July 2025, and roads will only be closed on those dates. 

After Vëlosummer 2025 ends, we’ll get in touch with you—most likely in late September—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 Vëlosummer 2025 yellow jersey will feature a brand-new design, giving it a fresh look that celebrates this year’s edition. 
It’s a unique reward just for 2025 participants!
