Bike ride indicated I went for a 14km ride when actually it was 54km. Timer said 45min when actually it was 3.5hrs. Heart rate comes and goes like I flatline but I'm still alive? What up!??
I've seen my heart rate flatline intermittently during a long run; I cured that issue by adjusting the wrist strap on notch tighter and positioning the tracker right between the radius and ulna bones of my arm just up from the wrist.
