My watch recorded a lactate threshold of 8:24/mile with a HR of 172bpm which is consistent with historical values. However in Garmin connect it is shown with the correct pace but a ludicrous HR of 46bpm.
This obviously is nonsense. I've tried deleting activities and reimporting without success in correcting the erroneous days in Garmin connect. I could live with it as a spurious point but it results in the axis rescaling making the plots worthless.
Any ideas folks?
