It would be great and very useful during mountain race to have a widget or an app for Fenix 3 that gives the instantaneous vertical speed in meters/hour. In fact, I found the average of the vertical speed given in the options of Fenix 3 but the calculation takes in account the overall distance of the track to do this. So, it seems to me that the real time instantaneous vertical speed performed during a ascent or a descent are not available. Someone find this idea interesting and able to develop a widget or an app for Fenix 3 ? Thanks for comments and answers !
