Yeah totally agree with this, I run regularly with a few friends, for me the pace is a touch slow but I enjoy the company and the chat, especially WFH full time.
Sure I could be quicker if I optimised my training but would largely be alone etc and I don’t race often enough to care.
For me Z2 is like 4:30km pace and probably run a 3:40km pace for a 5k.
I feel like the Spooner™️ bike zones also work well with running (swimming for that matter too)
Easy
Medium
Chewing stem
Three zones is enough for me.
Zones don’t work with swimming 
Its either zone 1 / recovery or max effort for the duration.
Dont get me wrong, I have gears to chose from…
Extremely slow
very Slow
Slow.
All out = slow +
Agree with @jeffb and @gingerbongo
It is better to get out there and enjoy it. No need to make it complicated.
Plus
Anything else is fine tuning.
Yes. It’s normal.
And who knows / cares?
Do you like running?
Just do some running.
For swimming I’ve embraced SheffSwim’s excellent advice to use nautical terminology. My training zones are:
Slow speed ahead
Half speed
Full steam ahead
And damn the torpedoes !!!
Fully on board with this, and others similar posts. Despite how prescriptive I made my training over 2022-2023, it doesn’t mean it’s for everyone, or all of the time. This social media fad of “zone 2 training” like it’s suddenly a new idea is more likely harmful, and at best unnecessary for the vast majority of people. The bandwagon will move back round to HIIT or something else soon enough.
Regarding paces, nowadays as a 22 minute parkrunner I’m doing all of my runs at essentially the same ~4:50km pace I ran “Z2” at when I was a 16:30 runner.
ramming speed
ah…you beat me to it…
there is no harm in setting zones…you can enjoy your running and be prescriptive…
but the idea that a 3:00 per km and a 6:00 per km would both have a Z2 of 90 secs slower demonstrates a lack of experience at the very least…
That’s when I mistime the wall 
Thank you everyone - tons of info there as usual!!!
Relly appreciate it and happy to continue shuffling along slowly building that base
There isnt… but if it is going to affect your enjoyment its better to do whatever makes you more consistent and enjoy it. Hence my comment.
Personally I love a mixture.
