So some background on my use with the HR built into my fenix 5x, training for a marathon I foound a lot of really weird anomalies using it. For example, running my dogs at a Z2 pace, I would see averages in the 160-170bpm. Then I could go do a tempo run and see averages around 120bpm. Neither re…

I have a Garmin 935. Running The optical HR is spot on. I found that I need to tighten it down one extra notch compared to when I’m not running to ensure a good reading. Also, I shave that part of my wrist. It works! :man_shrugging: About the only time I’ll wear a chest strap is if I’m racing. C…

I’ve have two heart rate only wrist straps (MIO Link and Fuse) : they can be as good as chest straps. The most difficult sport to do is Swimming (the MIO Fuse has a memory), but once you have cracked that cycling and running is easy. You can’t wear it where a watch goes though, which is where these…

I’d used a Garmin Vivosmart 4 earlier this year and the HR tracking was substantially inaccurate compared to chest strap during cycling activities. It was OK during all-day. I use a Whoop now and the tracking is accurate, though I’ll use a bicep strap most of the time during rides. I did test on wri…

My Apple watch is generally within 1-2 bpm of my Wahoo chest strap whenever I glance it it during an indoor ride. I’ve never tried it outdoors though. As others have said, it helps to have the strap tighter than you would for normal wear.

Your mileage will vary. Depends on how you wear the wrist sensor (how high/low on the wrist, how tight), your skin (color, hair, …), the sport (vibrations or not, loads on the arms/hands or not), ambient lighting (yes, even that - there can be interference with the sensor), and so on. In general, f…

Wrist based are functional enough to give guidance on your training, which is the limit for which aid use HR data anyway. In the early days I though several bad readings in a session were significant , but they average out. And if you get a prolonged bad reading, you can see it in the graphs or edi…

Discussed this very topic with a co-worker a while back. Comparing a Wahoo TickrX to the Garmin Forerunner 935, it seems that (for me) the “trend” was similar, but the wrist sensor lagged during warm-up and cool-down. Images below are from the same easy TR ride. chest strap HR: [chest%20HR] wris…

How are you able to log both wrist and chest heart rate? Does it to it natively on the watch?

The chest hr monitor can be paired to the watch…and unpaired. :wink: Did a TR ride that used the chest monitor and logged to Strava. Recorded an indoor ride on the 935 and logged it to Strava from the Garmin Connect app to compare. Then paired them back up for next time.

The HRM on my vivocactive is ok until I do any proper exercise. Use a chest strap if you want accurate data.
