I think the layout on mobile should change a bit. The recently completed streets should be under the recent activities. This is, what the page for a particular city looks like on mobile:
The interesting (for me) part is in the last bit where I can see my latest runs. Also, as it is a page about a certain city, I think at the end there should be the top striders for that city and not in general.
Oh, this isn’t a page about a specific city. That’s your default city (changeable from your settings page). The list of streets are those that you’ve recently completed - if you had run in another city, those would have been listed there as well.
