I am also having this issue. It's very disappointing as I do a lot of home workouts and basketball, so distance doesn't exactly help me. The other problem I noticed is that the workout calculation the site use are based on distance and duration, not heart rate. I have not looked through all the listed workout categories, but the mass majority does not calculate based of bpm. I've read that Endomondo might do this, so I'm eagerly awaiting the release of their app.
