"Trail Run" not influencing lactate threshold? Where else is it different from the "Run" activity?

Hi,

I've tried several times to run a LTHR guided test, with the "Trail Run" activity, and it always fails at the end (wearing a Garmin HR strap, of course). However, it works with the regular "Run" activity, which also updates the LTHR automatically from time to time.

If LTHR is not supposed to be updated when trail running, why is there an option to run a guided test when choosing that activity?

Besides LTHR I haven't found any other differences between "Run" and "Trail Run" activities. Does anyone know if there's any advantages in choosing the "Trail Run" over "Run" activity when I'm actually trail running?

Thanks!

    Another one little Bug?

    Yes, you able to disable VO2max calculation on trail run. It can be useful if you do some exercises in the sand, gravel and so on and not will drop your stats.

    Thanks for your reply . I run 99% of the times on trails, sometimes with some steep climbs and descents, and my VO2max improves when I train harder and more frequently. Why should I want to disable VO2max calculations on trail runs? I understand that the values would be different if I ran mostly on roads, but I don't care much about the VO2max value itself, but how much my training (or not training) is influencing it. Does it make sense at all?

    You don't have to, but you can if you need it. If you don't need it, don't turn it off.

    Yes

    Quite often on trails your pace will be slower or at least a lot more variable per effort as you look for solid footing/slide and generally concentrate much more on where you're putting your feet.

    This will mess up VO2Max calculations which is why its not recommended as such.  Its not even going to be the same for all trail runs as the terrain is going to have a big effect.  You'll end up with a random mishmash of results.
