How do you navigate a route that starts and finishes at the same place

I am importing routes from Komoot which has the ability to do looped routes so the start is the finish. I have a looped route that I’m trying to do. So I go to the start of the route and switch on my garmin I go to start navigation on the Edge 530 then it says I’ve reached my destination and finishes navigation. How do you stop it from doing this when the start of a ride is also the finish point? Surely this is a fairly common type of ride that people do.

    If you are creating your own routes, it's easy to make the route a bit short and it reliably avoids the problem.

    The units sometimes end-up sorting it out but not always. Restarting the route while moving seems to make it more reliable.

    ========================

    The Garmins also have an issue with out-and-back sections fairly regularly.

    I think what happens there is the variation in GPS readings causes the unit to think you have reversed direction. That is, it somehow thinks you did a U-turn. It then picks the other leg (it's clearly picking the other leg).

    I think the way to deal with that problem is to separate the tracks a bit.

    That is, relocate the track so it's at the side of the road (not the middle). I have some evidence that this works. And I have an explanation (a hypothesis) that makes some sense (I think).

    Doing this is, unfortunately, not so easy to do. It might be worth doing for a TT.

    The key thing to keep in mind is that the unit needs to know your heading to pick the correct leg.

    One reason I think something like I'm saying is happening (the unit thinks you've made a U-turn) is that restarting a route on an out-and-back appears to be more successful if you doit while you are moving in the right direction.

    Note that most of the units don't have compasses and need to be moving to know correct heading. For these units, heading is determined from succeeding GPS positions. When not moving, these measured position keeps hopping around, which means the the heading keeps changing too.

    Separating the track would make it so that your current position was always closer to the correct leg (remember, the units pick the closest point on the track).

    Thanks. Ill try to plot my TT course again. If i'm doing a club ride to a cafe stop and it's an out and back route i just create 2 files and load the second one at the cafe. Not practical for a TT though !

    The out-and-back problem isn't that common and it's usually easy enough to just deal with it. Which makes the effort of preventing it not so worthwhile.

    The effort would be worthwhile for a TT. 

    Someone here had the issue with a route they did regularly, which makes it worthwhile. He did what I suggested and it appeared to work.

    The endpoint problem is easy to fix for your own routes. You just have to remember to do it.
