Implement a new metric for running workouts (or also others): Mountain Index = Elevation / Distance
I have seen this on other platforms and it helps to classify running workouts / races better in terms of elevation, i.e. if you preparing for a 50KM 4000m elevation race (mountain index = 80) you can plan workouts with similar mountain index (i.e. do a workout of 30KM wi 2'500m elevation = mountain index 83) in order to reflect approx the same race conditions without going all the distance of the race. Also if you take the average mountain index of all your trainings etc. you can see if you are under- or overtrain for the upcoming race in terms of elevation.
Hope this helps - would be a nice feature for Ultrarunning - not so needed for road running though. But since the data is already here anyway, maybe something worth to implement in the near future or also take this into account when calculating "Hill Score"
