Max nav points

I believe course points are the ones that give you things like turn indicators as you approach them.

I think you will still be able to follow the course on the map screen but won't get those indicators after the first 50.

You can import GPX files now into the Courses section of GC so you can (hopefully) see where these course points are and even edit/delete some or add others.

That's interesting. The route itself was imported yesterday or the day before (into the new looking Courses section of the GC desktop site) and it actually shows up as having no course points. I didn't realise they weren't the actual nav points that the route is based on; in fact, given the choice I'd rather have turn by turn switched off anyway, and just have it as a route to follow on this occasion (as the race is marked; it's the elevation profile - and my position on it - that's most useful to me nav wise.)

Well no need to panic at least, thanks. Something doesn't quite add up mind - if GC shows no course points then I wouldn't expect this issue. I've deleted and re-sent the course itself to see if that changes anything but it didn't. A shame really as course points in principle as it appears they are intended on GC (to show aid stations, hazards etc) could work very well if implemented properly. But only if they can be added to a .gpx that wasn't created in GC.

Suggest post the GPX file here so we can see what is in it. Did you put the GPX file directly into NEWFILES on the 935 and so it parsed it or did you import from GC from your imported file?

Same question as Tim - did you send it to your watch via Garmin Connect, then get the course point question?

You can't see the course points for general turns on the Connect course creator, only extra ones you create manually for things like feed points on your ultra.

I've also tested to import course with course points to GC and found out that it didn't work.

​​​​​If you still want to reduce number of course points, you can probably do so by importing it to GPSies.com.

Here's the link:

And I imported the file from that download link.

I've downloaded in the following formats:
.gpx
.tcx
.crs
.fit

The .gpx I imported through GC; everything I've described above in terms of course points refers to that file. I took the same approach with the .tcx file with the same outcome.
The other formats I tried copying to NEWFILES (didn't show up on the watch) and COURSES (ditto.)

Thanks. Lots to talk about here.

When you import a course into Connect like that, as phoglund says, it will ignore any course points included. The course points being sent to your watch were created by Garmin Connect automatically. Because it's a pretty long course, it's decided that you need 117 turn warnings along the way, and your watch doesn't support that many. You can either generate a course using software that lets you control the exact number, or you can cut it up into smaller sections and load each in turn (start with Start>Run, wait for a GPS lock, select the first course from long press up>Navigate>Courses, then move on to the next one in the same way each time you reach the end of an earlier one. Should work, test it before your ultra of course).

Ignore the .crs format, it's obsolete.
tcx is not much use as it stands, as the 935 can't parse it, but you can convert it to a fit file with the right software.

You should just be able to drop the fit file into your newfiles folder and have the watch ingest it, and I don't know why that didn't work. For that matter, the same goes for the gpx file - was that a track or a route?

How did you export the files? From that page, looks as though if you want the course points embedded, you need to select the format, then click Show options, tell it how many course points and tick Add cue sheet, then download from that window. I can't see the tick boxes for types of download that my own tracks show.

The FIT file I exported with the coursepoints in from gpsies looks OK to me, can't see an obvious reason for it not to work. Might play later when I have my cable.

I looked at FIT files exported in various ways, and they all showed up in my watch, but with a total distance of 0, because the lap record at the start doesn't contain the distance. One claimed the distance to the first turn was 73.16 miles, which looks like the total distance, and Training Center is completely freaked by where the coursepoints appear in that file. I don't think I'd use either of them myself.

The TCX looked better after conversion to a FIT file, but I didn't think the coursepoint positioning was very helpful; there's a point where you're doing hairpins up a steep path, and it gives you a turn alert for every hairpin.

If I were you I'd be inclined to use the course you've got in Connect already, and not pay too much attention to the turn alerts. Pity you can't turn them off and just use manual points for feed stations and so on - that'd be ideal in your situation.

The new GC course points are bizarre, why would anyone design a feature that was more helpful turned off? But can't be turned off. I'm sticking to my Ultra.

RTWtool will show the course points added, but hidden, by GC.

I'm inclined to agree - both in sticking with what I've got now through the .gpx and in terms of the potential that's there, but not quite yet realised.
