Endurance score - ignoring a marathon!

It looks like a treadmill run doesn't contribute to endurance score? Is this correct?

I ran an indoor marathon around a disused prison on Saturday, and my Endurance Score has just totally ignored it. I started as a normal run, but then switched sports to 'treadmill' when the GPS failed (it was 95% indoor). Surely that's a major bug in this metric? Or am I missing something?!

    Yes, correct. VO₂max and all derived metrics (Endurance Score including) are only measured outdoors with a GPS signal. See also the document support.garmin.com/en-US/?faq=lWqSVlq3w76z5WoihLy5f8

    Indoors, there is very little to no chance to get a reliable GPS signal. It is not a bug, it is how GPS functions. And if you mean he lack of Endurance Score at treadmill running, then it is also not a bug. It is intentional.

    Why on earth is that? I was wearing a heart rate monitor, and took distance from the internal gyros. Same for VO2max - I usually wear a footpod and get very accurate pace. Why does the garmin need GPS?! 

    This will also mean that treadmill interval sessions wont impact the VO2max data in the watch. Sounds like a major flaw to me.

    I wonder what would happen if I had the GPS enabled, but set both distance and pace to the footpod?

    It is how it is designed. We can only speculate why, but most likely because Garmin does not trust the accuracy at indoor running sufficiently.

    I do not have Enduro 3, so cannot tell for sure, but when I tested it with my Instinct 2 and HRM-Pro (also delivering pace & distance), it did not work. What did (sometimes) work, was locking the GPS outdoors or in the proximity of a window, and starting the outdoor Run activity while running indoors. The sensor setting for Pace & Distance had to be in the mode "Indoor" (not "Always" !). The watch uses the sensor even during outdoor runs, when GPS signal is insufficient.

    I think "Indoor Run" may have been a better match than "Treadmill Run".

    While VO2Max changes do require a GPS signal (treadmill speed and distance are notoriously inaccurate, and IMHO Garmin are right to exclude it), most other metrics should use your existing VO2Max.
