How is a tempo run Training Effect defined ?

I'm puzzled as to how my Garmin 945 is classifying my runs, specifically the Training effect primary benefit.

For example, this morning a ran 2kms at 6.30 min/km and spend 80% of the time in HR Zone 2 (the rest was Zone 1).

I was expecting this to be classed as Recovery or perhaps a Base run but it is showing as a Tempo which feels wrong.

Does anyone know how the formula works to determine the primary benefit Training Effect ?

    Glad to hear things are looking better! 

    I don't know if it was associated but right around that time is when the Garmin servers were really jacked up, especially with training status and things ike that.  could have had some bad info from that... likely not...but who knows.

    I had this exact thing happen to me on Tuesday. I went for a run that was easy pace (and has always been classified as such). When I looked in "heart rate zone," it said 80% of the run was in z2 or easy pace. But "primary benefit" was tempo. I think there is some sort of bug/glitch in the software. So I contacted Garmin customer support. They've sent the issue to engineering. They suggested telling people who are experiencing this to report it to them so that they can get more data to figure out what might have happened. If you're still having the issue, I'd definitely suggest reporting it: [email protected]

    Just sharing my experiences. I set my running zones as following:

    z1: 65% to 85%

    z2: 85% to 90%

    z3: 90% to 95%

    z4: 95% to 100% of MHR (= LTHR)

    z5: LTHR to MHR (Detected by Garmin)

    I am getting base training effect if I keep my runs at z2 or below.

    Tempo, threshold or vo2max training effects if I keep my runs at z3 and above (ie fartlek or tempo runs).

    Anaerobic training effect if I do my speed intervals.
