Sorry, Zeal, you'll need to elaborate.

What do you mean by 'completed journeys'? CT does not record our cycling. If you use a gps unit or an app like Strava you can record your cycling data & route - but you'ĺl need to import that into CT.

Can I upload a route that was plotted on another app ?  If so, which folder on my phone should I drop it into ?

Answering my own post ... just found the Upload on the Map page ... and it appears to work.  

Sorry, but I'm absolutely new to Cycle Travel.  Looking promising.  

OK - now I've played a bit more, I can see that I've hijacked Zeal's thread.   

It could be that he was wanting a route (Journey) folder specifically for completed rides ... and CT move the route there automatically when completed ... or maybe he/she meant something else
