Last sunday I was running on a trail.
I downloaded from ConnectIQ a datafield showing the total ascent during the activity.
That data is not avaible on FR230 elevation datafileds by default
I noticed that also on activities history details there is not the total ascent data.
One thing to note about this, is the 230 uses GPS for elevation, total ascent and total descent, which can be quite a bit off. When you upload to Garmin Connect for the fr 230, it applies "elevation correction" to give you much more reasonable numbers.
One of the screens in my hiking app displays elevation/ascent/descent, and I'll walk 1/4 of mile on flat ground, and it could show an ascent or descent of a 100+ feet on the watch, but GC will correct my elevation gain to a few feet at most.
