I've requested this before, and I still really don't understand why it can't be done. Why does garmin connect insist on adding the total distance for all activities for the weekly total? This is silly. The only reason I would want to know a combined distance is for a "fun fact."
I've ended up not recording my totals for biking at all in the garmin connect calendar because I don't want it to affect my running totals.
PLEASE update the calendar so that weekly distances can be separated by category.
