It seems to make much more sense to me to have a collection of tuples
that contain time, position and heart rate. The heart rate isn't
connected to the position in a 1:1 relationship. At a single position,
you may have more than one heart rate, at different times. Of course,
you can plot an excersise on a map with the heart rates attached, but
that does not make it logical to relate them directly.
