As a runner, specifically during training seasons, one of the main data points I use to track my progress is my improvement in pace (min:sec/km) over the season. It would be helpful to have a visualization of my average run pace over time in the "Progress" section on my profile.
This "Pace (All-Time)" trend tracking could be displayed as a plotted line graph widget. The graph could be set up so that the x-axis represents time (weekly, monthly, or annual display mode options), and the y-axis represents aggregate average pace (min:sec/km) from all logged run activities.
It would be helpful to see a few different lines plotted on the graph that represent pace per different categories of run distance. I have suggested a few run distance categories below, for example:
LINE A: "short distance" (0km-10km activities only)
LINE B: "moderate distance" (10km-25km activities only)
LINE C: "long distance" (>25km activities only)
LINE D:"all distances combined" (average of all logged activity paces for all distances)
