Hi ... I just returned from a long ride and, by accident, stopped and saved the first portion of my ride. The first activity was saved and I could not seem to restart the time in that ride. So I started another activity and finished the ride. Now there are two activities, the first half and second half of the ride. My question is can the two activities be stitched together so that the first and second parts of the ride and be made into one, as I intended?
You have no idea how much I know what you mean...this happened very often to me when I still had the Forerunner 620 where the save-button was more or less over the whole screen when paused. Combined with the touchscreen and the the absence of a screenlock-feature an ideal point of failure...
Is it possible
Yes and no. There are third party tools to do this...within connect you won't be able to do it. With the increasing complexity of the xml-files I didn't really have success anymore towards the end and gave up. If you still want to try it proceed as follows:
1. Download your single training-parts (the fit-files)
2. stitch them together in third party software
3. re-import the new file as a training and delete the old files
Which tool to use?
The tool I once used is not online anymore...well, probably because it didn't really work anymore. I am a software engineer and implemented my own tool to do it with mixed success. Problem here is not stitching together the single data-points but calculating all the average values, hr-zone totals and so on. I was not able to get the same values I would get when recorded as one piece. There is a specification for generating fit-files and what value to put where, but it does not include the garmin-specific calculation algorithms for obvious reasons ;)
Can others do this?
I remember the old polar-software (not the new online-portal) had this feature and since then...I don't know!?
How to prevent this problem
If your device has the possibility to lock the screen when paused...do it...EVERYTIME! Since I have the 920xt and an Edge on my bikes (both having this feature) it never happened to me again.
I know this is not the answer you were looking for, but I just wanted to give you an idea about the complexity of it.
I'm pretty sure you can just export them both as .tcx files, then copy everything from the 1st <trackpoint> to the last </trackpoint> in the later file into the earlier file after its last </trackpoint>, then manually edit the total / average / maximum values, then import the file you've put together.
