When I go for a run, if my heart rate gets the the 'peak zone' it becomes very inconsistent. It will display two lines -- instead of my heart rate then as my heart rate slows down it starts to register again. It's frustrating as I don't know if my calorie burn is accurate.

A warm welcome to the Community @HayleyLarge94.

If you are having issues with your heart rate information while running, I recommend taking a look at this post, where you will be able to see some things that might be affecting this reading and some tips to improve it. Also in this other post, are more tips on how you can wear your Blaze while exercising.

I hope this helps, let me know the outcome. Robot Happy
