Another idea is to see in the same graph info about the height and speed. As usual, I parsed with R a tcx file downloaded form Endomondo. I generated a data frame with info of the distance and the time spent on each GPS position. Then, the speed is calculated and is measured in km/h.

If I mix in graph the attitude and the speed, we could see the next picture:

Maybe, it is a strange example, because I haven’t increased my pace when I was going down and I could conserve my pace when I was rising. I will look for another example.

Finally, it seems interesting to see the height (attitude) in the map:
