I guess this is what Chris means by soft and comfortable. That's from my 9-mile run this morning. Actually, the strap itself is very very comfortable. The problem is that the pod with the electronics is relatively heavy. Kind of like how Polar's stride sensor is such a Goliath compared to other foot pods. That's not an issue when cycling, but when running it has more momentum as it (or, rather, you) bounce up and down. As you can see, it doesn't take long for that become painful. (And no, I'm not wearing the strap especially tight; in fact, the problem is worse if I loosen it.) OTOH, it probably says something about my running form too. I guess if the H7 doesn't support running dynamics directly (like Wahoo or Garmin) I have an indirect indication ;^)



For comparison, my H7 electronics pod without a strap (but with a battery) weights 26g. The Wahoo TICKR Run (same conditions) weights 16g.
