Anything over 9 miles or so and my chest gets a gnarly rash right in the middle of my chest where my HRM sits. I put a decent amount of body glide, and no change.

Anyone have a way to combat this?

      I had an older model watch that required a chest strap before that. I think it was my old Pebble. The way I tested was I wore the two watches at the same time and pulled the chest strap data from the older watch and compared it to the wrist monitor data from the new one. I couldn’t see any meaningful difference over about a week of running, so I happily gave up the chest strap.
