How many of you wear your HRM while racing? The reason I ask is that it seems to me, may all be in my head, that when I notice my HR is high I "lose" energy/power. I may be in a high range but if I don't notice I feel fine as soon as I see it though it's as if I lose something. Is this normal?
I would like to keep it on to look at the numbers after the race but there is no way on mine, Polar CS100, to have the HR on and not displayed. Any ideas? TIA!
