I saw a pop up that said I unlocked some kind of a challenge during my ride a couple of days ago. Where do I go to see more about the challenge and how to earn it?
After doing more reading, I am pretty sure that it is the Italy challenge because it sounds like you unlock that when you get to level 10 and I did just get there recently. On the Main Menu screen, I do not see anything to choose beginning that challenge and I do not know what the requirements of the challenge are. Any info on this is greatly appreciated. Thanks!

To complete a challenge, all you have to do is ride/climb the distance/elevation shown on the challenge image. The rewards are for you to discover on your own.
If you want to change your challenge or see more information about them, see our KB article.
