Total Mileage Calculation (Read 65 times)

In my group we track people's total mileage for walking, biking, swimming, and running. At the end of 6 months, we give them a TShirt for which "club" they reached; 150, 250, 300, 350, 400, 450, 500, 750, or 1000. The issue is, in the reports section, it only counts mileage if the workout was logged as a run. I need it to count all the distances. Even on my personal page, I added a 200 mile swim, and my summary doesn't show it in my mileage totals. Why is this? How can I fix it? Thank you.
