Jumping on Train on route - how do I remove from Course?

An activity can't have any gaps. Stop the ride and save. Ride train. Start a new ride.

You can just stop the ride when you get on the train and then start again when you get off the train but you will get a straight line between those points. The stopped distance will not count to your ride.

I may be wrong, but it looks like you are speaking about your regular commuting trip, if I understand well. Why do you want to use the Course for it exactly? The purpose of Courses is navigation. You will not get any stats, ranking, or records at Courses. And I suppose you do not need to use the navigation for a trip you do regularly. Rather use Segments for that purpose. You can create several short ones along the route. It does not need to be in one piece.

Thanks for reply e7andy. I did as suggested and it seems it worked - though when I have the final activity uploaded once all finished,  it doesn't show the km/mile markers at each 1km/1mile interval so not 100% sure if in the end the distance of the train journey (which as you know appears as a straight diagonal line) has been counted towards the total distance count of the activity.

I suspect it hasn't added it up. I also run Strava as a back up and that seemed to add the train journey to the total distance and the Strave activity ended up being longer in distance than the Garmin one so perhaps Garmin did exclude the train journey.

In edition when I stopped the Garmin it kept resuming activity a few times during the train journey. 

Thanks for reply trux. Your comment is absolutely reasonable and logical if I was doing a regular commute trip e.g. to work.

However this is what I am doing: I am doing a workout/training route and need stats and also using navigation for an unfamiliar route.

The reason I am jumping on a train for a 15 minute ride is because I am in Italy - the majority my planned route goes on  quite a picturesque tarmac cycleway through Rome and then its suburbs down to the coast- but at one point the cycleway ends and it becomes muddy/gravel path. 

The tramac cycleway then restarts further down before the coast. Now,. I am riding a road bike with road bike tires. The alternative on not jumping on train and just cycle on the road is not idea because the road that would take me to the other half of the cycleway is a notorious A road and I don't feel safe on this segment. So I decided to to one segment on a train and continue further down.

Yes I could, that is a good suggestion.

I did some research on then how to then combine activities on Garmin so it counts as one activity /training for that day (it could technically end up being 4 activities  as it will be a outbound and return along same route so = out A1 + out B1 + backB2 + backA2), but it seems a complicated operation or Gamin connect doesn't offer this edit function?

As I wrote - you will not get any stats or ranking at Courses. Use Segments for that purpose. And as for the navigation - I guess you do not need any navigation for going to the train station, so just skip that part, and only create a Course for the part from the destination station. There is no need to make the course for the entire trip - you can start the navigation anytime during the trip, so just start it when you get off the train.

If you want to avoid the straight lines on the activity map, while you pause the activity and take the train, I suggest using the Multisport feature - ride to the station, pause it with the choice Resume Later, and when starting from the destination station, start a new multisport "leg" by using the option "Change Sport" (selecting cycling again) and then Resume. In this way, each part will be stored with its own map, while the two parts will be listed as a single Multisport activity.

Thanks for further clarification trux, I will see if I can implement your suggestions on my next ride.

Having said that, I do get stats on my courses once I ride them and they show up in Activity. I see Distance, Time, Speed (all I need), as well as Speed/Elevation/Temperature charts, nutrition etc. Ranking not sure what that is (perhaps how fast I do a segment compared to other riders) - this I don't see.

It is also a shame that in Activity the highlighted corse does not show km/mile distance markers as it does when you create the course.

Not sure whether I understand you well, but the information you describe, is not data of the Course (navigation), it is the data of the Activity (workout), that you get regardless whether you use the Course navigation or not. What I meant are statistics for multiple passes of the same course - such as frequently going the same route to the station, and wanting to see your ranking and stats through the history.

At Segments, in contrary to Courses, you can review the history of all your passes through given segment, and see how you performed in comparison to your historical rides (or runs).

Again, I am not sure whether I understand, but if you use auto-laps (by default each 5km at cycling), then in Garmin Connect Web, you can turn on the Lap markers (each 5km) on the map. You can also change the auto-lap to a different distance, if you wish. In Garmin Connect mobile app, the markers are on by default on the fullscreen map.
