The Total Distance report today shows a pretty graph with days or other time periods across the horizontal axis and miles on the vertical axis. You can hover over each vertical bar to get the miles run during that time period.
However, especially when viewing the seven day view, it would be really nice if the report displayed the total miles run for the whole week. This is less useful for the 4 week, 6 month, and 12 month views, but since many training plans discuss miles/week and have strict recommendations of how many miles you add per week, it would be great to have the total miles per week in the default 7 day view.
This is one of the reasons I link to mapmyrun, and it would be easier if I could get the total miles in the last week in the default 7 day view.
This feature would be nice both when the graphs are displayed in the main dashboard and when they're displayed in the single-report view after you click on the graph in the dashboard.
