High HR starting indoor cycling

revcp

Very odd thing going on. Winder in Minnesota, so when I’m not on my fat bike outside, I’m on my trainer in the basement. I’ll take a HR reading on the watch, all good. I’ll start tracking indoor cycling, HR starts out in 150s or 160s. After five-ten minutes, is goes back to being accurate. This does not happen when I track a walk or hike, just the indoor cycling workout. Anything I might be doing wrong?

Hello, thank you for sharing your experience,
But did you use the watch ohr sensor?

If yes, it’s totally normal, OHR needs time to stabilize the reading, if you want accurate hr value, please use belt sensor

Yes, OHR. I always make sure the OHR is picking up accurately, but when I switch to indoor cycling it spikes and stays that way for 5-10 minutes, so effectively ruins the ride. I would use the chest strap (I have a Suunto unit), but it seems limited to being read only by the watch or the tablet I have hooked up to my Tracx trainer. It won’t link to both at the same time, so I have to rely on the OHR for Suunto and the chest strap for my trainer.

@revcp maybe gripping the handlebars too hard at the start?

Not gripping them at all. Riding upright, hands off bars, looking at my watch while I wait for it to drop from the 180s to 80.

I’m actually nearly certain that it’s the indoor cycling exercise that’s the problem. When I use regular cycling or mountain bike cycling and turn off gps, all is well. I’ll just do that from now on, but note to Suunto, please fix for the next upgrade!

Anyone has this issue? @Bulkan did you use indoor cycling?

Well, I use it without any issue, but I’m a poor old spartaneer

@isazi I’m doing indoor cycling regularly and don’t have this issue. Once or twice I had lower HR for the first few minutes but I think that I started the activity immediately without waiting for HR indicator to stabilize first… When I wait for it to get stable, than it works OK.
