@rbrbrb2 You and I are very similar, it sounds like! The highest I've seen is 207, and when I do a race or other long, all-out effort, my HR will be in the 180's.
If you want some numbers for a gut check: my easy runs are around 140-150. If it's a hot day (heat affects HR) they might get up to 160 by the end. If I'm running at 170+ HR, then that's a tempo run or something else that's higher effort than an easy/z2 run. And if I'm above 180 that's a race or an interval--so definitely not an everyday sustained effort.
