Hi, I have a Wahoo TRACKR chest strap HRM which works perfectly when I’m out walking. However when I go running it often shows a really low heart rate for a few minutes and then jumps back to giving an accurate reading. Since it works OK for walking I must be using it correctly.

Has anyone else experienced erratic TRACKR readings when running?

If I don’t wet the pads first sometimes that happens.

Moistened both body and strap before today’s run and it worked perfectly - thanks for the tip!

Use Tickr chest strap for cycling. Often didn’t record anything at start of rides until I started wetting the electrode pads.
