Strange increase in HR during running

5858725 4 days ago

HI all! Yesterday I was running at ca. 120 bpm, while suddenly HR went to 140 without changing pace!

I do not use the strip, just the watch, and just some seconds before the HR increase I holded more narrow the watch strip... see below...

This increase could be the cause of the strip was not narrow ?

Thanks

What do you mean by strip?

He means strap.

Ok, makes a bit more sense. Seems like the strap wasn't tight. Should be snug, but also not too tight.

Yes, the strap of the watch wasn't tight, when I holded more tight, there was the HR increasing... I think I need to buy a chest strap, but I read somewhere that it could be annoying because it tends to slide down the chest. What's your experience on this? I saw a chest strap with an additional strap up the shoulders

The Garmin straps do not slide down for me, but I guess it depends on how you are shaped. I guess it is worst if you have a very slim waist and wide chest.
