Hello,
Just a suggestion for the pace (running) graph within activity details -- When viewing in Distance mode (x-axis is distance) and hovering over; the system show the distance and pace at that point (see screen capture) below:

However, it would be really nice to see your cumulative time at a given point along the x-axis -- so you could see how long it took to get to a certain point; for example in the image above, the hover bubble would display the distance at that point (16.11 km in this case), but also the TOTAL (cumulative) time to that point.
Hope that makes sense.
Thanks!
