Anyone else have problems "pausing" the Garmin 310XT?

Hi,

Not sure if it is just the unit I have but I noticed during today’s ride that if you pause the 310 by hitting the stop button, say when you stop for a water refill etc. during a ride, it messes up the data recording. You get strange graphs with a long time gap of no data recording that corresponds to the duration of the stop.

It seems as if the 310XT is using clock time to record with the data, rather than stopwatch time, which is fairly useless.

You can see this when looking at the raw data as shown in this screen cap. i stopped the bike and the stopwatch at 1:29:08, and restarted the stopwatch 18 mins later. Instead of resuming the data record at 1:29:09, you see the problem…

I pulled the file into WKO+ and Saris Poweragent software and there is the same problem with how the time is recorded, so the same weird graphs as Garmin connect displays:

i contacted Garmin but they said the same thing about the last problem I encountered, being unable to download my previous workout, which was to perform a hard-reset. Of course, I had done this just before the ride, so it really doesn’t address the issue.

So far, 1 week into my Garmin 310XT test…1 workout completely lost, 1 incident of the watch popping spontaneously off the band (thankfully, when wheeling my bike to the start of the ride), and now noticing this strange time stamping.

Any thoughts? Getting discouraged.

The 310XT will display:

Time = stopwatch time and
Time - Elapsed Run Time = Total time including pauses or stops.

These are separate data fields, I think you just need to tell it which you want to see. When I download to Training Peaks, only my elapsed ride time is shown, not the total clock time which includes pauses. The graph does however show the total clock time.

As far as retrieving the older data, the 310XT defaults to sending only the last workout. You need to change the Mode>History>Force Send>Yes setting for it to do what you want.

So, you are saying that you have the same problem as I do with your raw data.

The graphs, and the raw data they are based on show total clock time.
