You might think this is a bug, but it is called a lead in. The Serpentine 8 route STARTS at the banner by the waterfall, not where you spawn near the top of the jungle.
Think of it like a local strava segment that starts 3 miles from your house. You have to ride to the beginning of the segment in order to complete it.
Www.zwiftinsider.com is a great resource for all the routes on Zwift, they include the info on the lead ins. In the game when you choose a route there is a blue line that represents the lead in and the white line is the actual route.
I’d just like to add my data point here. I believe there is something a bit broken with the route.
It took me three attempts to get this badge. I believe that each time I did the same thing, selected the route and rode ~30K which is longer than the lead in plus route distance. But only on the third attempt did I finally get the badge.
Not aware that I’ve ever used manual turns
Not logged in on more than one device (except phone for companion app)
Didn’t turn any corners I don’t believe.
23rd, 24th, and 31st were the activities which should be visible. Looking at the replay it seems like I turned around at different points on the first two attempts, but this wasn’t deliberate. Hopefully this helps anyone looking at the issue.
I still think it’s a design issue that the interface doesn’t just tell you how far you have to go and what route you are on. It tells you distance to go in time trials, for example. It’s just not clear. You get used to it in the end. So not technically a bug (since it’s working as designed), but couldn’t the design be better?
For completeness, just to mention that you can apparently also fail to get badges sometimes if you have Zwift running on a second device at the time of your ride. I have it on a PC that’s not in a suitable place for riding, as well as on a tablet, and have to remember to shut it down on the PC if I’ve been using that to plan routes or whatever. However, there’s no reason to think that that is the cause here.
For Serpentine 8? It doesn’t look like a banner, but there’s an archway near to where the Jungle Circuit lap counter is (normally reads zero unless you’re doing loops there), near the caves and waterfall. You’ll get a powerup every time you go through it.
