100Km Radfahr Challange mountainbike aktivitäten nicht angerechnet

They are counted. All types of biking counts. The 100 km challenge for July starts July 3.

Was it MTB rides in June that didn't count for the June Ride to 100 challenge? 

MTB in june does not count for the June challange but road cycling is counting.

Can you post a link to one of the activities that didn't count so we can have a look at it? 

I hope this works:

But this one does

Total Km in the challange is still 40.7km

The June Ride to 100 was only June 5-11. That is why the MTB ride didn't count but the road bike ride did. 

I can't believe I didn't see that, rookie. That was a short June. Thank you so much!!!

The 100K challenge is for a week. The 200K is for two weeks. The 400k is full month.

The next 100K starts on Sunday and runs until Saturday next week. Easy to miss it if you wait. I'm on vacation without a bike so the plan is to do the full 100K on one go as soon as I get back home with very few days left of the challenge.
