Running

Is 160bpm too high

don't compare to other people, it wont give you any useful info

there'll be people running slower than you for lower HR
there'll be people running slower than you for higher HR
there'll be people running faster than you for lower HR
there'll be people running faster than you for higher HR

that said, if you were doing race efforts and not going over 130bpm, or not dropping below 200bpm then I'd suspect either a dodgy HRM or something to get checked out, but 160ish for some effort is entirely within the realms of normal. keep going with the zone 2/3 and see if you're running faster for same HR or same pace for lower HR in a month or so

Thanks for the answers. I mainly compare it to my cycling heart rate, on the bike I have to push hard to get to 160 and I normally sit around 130-140bpm.
But this is new for my body and I don't have the physique of a runner...
I'll just continue like this

I've never been able to get my HR on the bike up to running. When I started running then tended to reach ~175bpm running and maybe 170 on the bike
I'm a better runner now (and probably a worse cyclist) and still have a higher HR running. If anything, the running has just brought the cycling HR down a bit further

Surely you can inside right? On the turbo.

When you're outside your heart does less beating because the wind is cooling you and there's less requirement on your blood to perform vasodilation.

nope, still lower. though there's a floor fan in front of the turbo so probably more of a breeze than outdoors

Different sports have different maxes.

Max swimming is ~185bpm (during some sprints https://connect.garmin.com/modern/activity/5643406465
)
Max cycling is ~185bpm
Max running is ~195bpm
Max 5-a-side is ~205bpm (highest I can find in Garmin Connect is 201bpm with a 183bpm average: https://connect.garmin.com/modern/activity/2583478721
)

I just can't get my HR up that high when cycling, including doing various all out efforts on an indoor bike with no cooling.

Ugh. Hate those previews...

Cool thanks for sharing!

The flip side of @Greenbank..

I would be at 125 BPM at 6.30min/km and 140bpm at 4.50min/km. I'm not that fit just have a slow HR.

I'd put the HRM in the drawer and run easy by feel. Don't be afraid to walk.

Almost the same length.

I'm the same, I've got to be doing a hard interval or FTP session to get out of zone 2 on turbo but will drift into zone 3 at least on a long slow run.
