I'm making a course for a long gravel race which passes roads and paths etc, which requires some custom hand-editing of directions. (The only really reliable thing for navigators for notifications are TCX course points, so also things like barriers etc on the course is added like "directions")
There are functions there to do that - great! There's just one small problem, when adjusting the location there's quite big jumps, even if you drag the icon in the map rather than using the slider.
I think the reason is because if your course is long each slider pixel jumps quite a bit, and you can only place it where the slider is.A really quick fix that would be good enough is if you make it possible to also edit the distance number by hand, that is the number 102.430 in this table (now only the text can be edited). Doing it in the bigger dialog would also be ok.
The only way to fix it now is to export the TCX file and than hand-edit the text file which is not great.

Hi Anders - if you turn on Keyboard Shortcuts in your Settings, you can use Shift+→ or Shift+← to make fine adjustments to the edit position.

Thanks, that's great, but it doesn't increase the resolution. In my 440 km long course each step is about 45 meters, which is a bit coarse when marking the location of a barrier for example.

Hi Anders.
Question: What navigators do you practically use? Garmin Edges or....any other ?

Anders,
A workaround, click "Reshape route" and add an achor at exactly the place you want (zoom right in). Then add a direction to that "point".

Also, choose the map that gives you the highest resolution for this operation

Willy: I'm a gravel bike race/event organizer, the navigators will be whatever the participants have, but of course Garmin Edge of various models is the most common. I use a Garmin Edge 530 to test the resulting file.
Unfortunately Garmin Connect strips the TCX file of any course points, so one have to use the old school method and load it via the USB cable, but that's okay, I can instruct the participants to do that. This is a problem shared by randonnée organizers etc, in any case you have a course defined by GPS track rather than signposted.
The goal is to provide a course file to the participants that contains a quality cue sheet with turn by turn navigation, plus warning of barriers, marking climb peaks etc.
What Garmin wants you to use is their automatic turn guidance and not have any third party course points at all, I guess that's why they strip the data when you import the file via Garmin Connect (they strip elevation data too by the way). The problem is that automatic turn guidance works horribly bad on rural gravel roads mixed with some paths here and there. It tells you to turn where there is no turn, and misses other turns. And of course the auto guidance don't highlight barriers, water food stations etc. Turn guidance works especially bad if the user have a map that doesn't 100% match the course (common around here, I recommend users to get openfeitzsmap for their Garmins, but not all do).
Long story to explain the need to be able to craft well-made TCX files which still is the best way to go for these types of events. TCX with course points seems to work well with Wahoo etc too. TCX course point presentation is primitive on Garmins, max 10 characters ie "turn right" is all you can say, not "turn right onto blabla street", but that's acceptable. There is data fields with distance to next course point etc, so it's fine. One just need to instruct participants with garmin devices to 1) disable auto turn guidance, 2) load the tcx file via USB.
To anyone interested in TCX files and custom cues on Garmin Edge here's a thread, the user L Rouge is well-informed and know much more about it than I do:

@Mark: tried the workaround with anchor, but it doesn't change anything, the anchor does not provide a new point for the direction to attach. Map layer does not change anything either.
What does "work" however is to alter the length of the course by moving start position slightly, say if you have a long course that yields 50 meters steps like I have, if you lengthen the course with 25 meters your new steps will still be 50 meters between each but shifted 25 meters from previous, so you can for a location you need to precisely place fine tune the length of the course by moving start position until it is possible to line up the direction where you want it, and then move to next you want to manually place and repeat the procedure.
The already placed directions get their distances recalculated when course distance change, and this is done correctly so the directions does not move (noticably) when the course change length.
However this procedure is *very* tedious. Would be nice to just be able to type in distance manually as the least, and have fine steps when dragging the icon rather than using the slider as the best approach. -

So after adding an anchor, you couldn't add a direction? Worked for me.
Map layer comment was just to give you the maximum zoom level -

Admin: I keep getting an error message about size of attached screenshot. It won't accept a 600 pixel width screenshot. Was not like this previously ....
