Lately i'm experiencing abnormal hearrates.
I'm running with my dog, the pace drops in the beginning are normal (pee stops from dog :) )
Point 1 is an abnormal peak of +30. I know my body well enough. These reads are wrong.
At point to I was fed up with high heartrate so i took of my watch for a few seconds.
Hearrate was reset and never went to the real level.
Not sure what the watch is showing here but it's certainly not my hearrate.
