actually I am doing different kind of sports: bicycle (MTB and street), trail run, run, off piste skiing and in order to select only one kind of activity i am used to set filters on the activity page.
I Think that an useful piece of information that is missing in this page is a kind of final line with statistics.
It would be nice to have a line like the one that is shown at the bottom of the calendar page showing the total distance, total time and so on. (please note that in the calendar there is no distinction between e.g. running and trail running and a lot of activities are classified simply as "other activity" so everything is grouped together)
Something that I can not find anywhere is the sum of the elevation gain (something similar to the total distance) for running. If you practice sport on mountain this is a much more interesting parameter than distance.
For these reasons I think that it would be worth adding a final line to the activity page with statistics. Obviously for some parameters the total sum is more relevant (e.g. for distance, elevation gain, time and calories) instead for other parameters the average should be displayed (HR rate, avg speed, cadence), for others, finally the global max or min values are of interest (max speed, HR max and HR min).
