Incomplete ride registration

I’m using Firmware 7.0
I’ve had the problem twice that an activity file contained only the first part of my ride (before the stop). However, the “total distance”, “(total stopwatch) time”, “elapsed time” and “calories” seem to be correct (for the entire ride). But all the other data is missing. The “moved time” (in Garmin Connect) is also incorrect.

What happens is the following:
1.I ride to work and stop (pause) the timer at work (by pressing the stop button and switch off the Edge 1030).
2.During the day at work, I power on the edge to view the screen without starting the timer. After that I switch off the edge again. (don't know of this matters)
3.After work, I power on the edge and restart the timer (and ride back home).

All seems to work fine. It looks like the ride is recorded. Then, when I arrive at home I stop the timer again and store/save the ride. However, when I check the Activity file I only see the track of the ride into work (before the first pause and shut down). The track back home from work is not recorded in the fit file. The weird thing is that the total distance and total time recorded are correct. So, it is definitely not a problem of forgetting to restart the Edge after work.

Most of the time I have no problems with recording the ride, but as said, I’ve seen this problem twice now. I’ve never seen this issue with previous firmware versions.
I’ve never seen the issue when I skip the 2[SUP]nd[/SUP] step.

Given the size of the files it would appear that a lot of data is missing, since the size is smaller than a normal commute ride.
I've attached a good ride registration and a faulty one.

Does anybody have any suggestions/ideas?

28-02: is a ride on the same route, but with the incomplete fit file
27-02: is a correct ride along the same route

  • I checked both fit-files with fitfile-repairtool.
    As you describe: the ride on 27.02. shows the whole ride. Power down at few minutes after 9:00 and power up at aprox. 17:00. Then another course back home - 52 km total.

    The fit-file for the other ride on 28.02. shows only the ride to your work. Power down few minutes after 9:00 - but no power up event. Power down is the last recorded event. And the fit-file only shows the distance to work - about 19 km - not the "whole distance"!
    So, finally, the fit-file contains only data for the ride to work - no data for the ride back!
  • Thanks for checking the fit files. It would then appear that the edge did not register the ride back home properly. I used the lap-button during the ride home, just as I did on the 27th. The timer and all other data fields were registering properly. Apparently the edge did not store the data into the fit file.

    The strange thing is that Garmin Connect shows the entire distance, but without track.

    On the 28-02 page:
    The graphs indeed show the first 19 km.
    However, the totals do show the entire distance of 56 km. And 2 hours of riding time. Some other totals, such as calories, are similar to the ride of the 27th. (I did not modify these values).

    How did this data come into Garmin Connect, if it is not in the fit file ?

  • Thanks, your research is very interesting!
    But as a conclusion - what do you think has happened if the fit-file shows a power-up at afternoon, has stored the whole distance but the ride itself was not recorded?
  • ah and my apologies for interfering :o


    No, no - every help to bring light into dark is apreciated!
    Thanks!
  • I had a similar problem after stopping for a mid ride coffee.
    I'd powered the edge off & when powered on again there was no track recorded for the 2nd part of the ride. Fortunately because I had a speed sensor the distance for the ride was correct
    I've never had any problems if I put the Edge to sleep at a stop instead of powering off. Maybe try that.
  • Thanks guys for the thorough analysis of this problem. Much appreciated.

    I'll contact Garmin Support to report this issue. I'll give them the data you've provided.
    Also, I'll remove the Max grade CIQ datafield and put the edge into sleep in stead of powering down.

    Thanks!
