It would appear that according to my watch data, that I analyses later, I have no clue how to pace either! Last nights run was possible the most erratically paced run I’ve ever recorded. It’s all over the place, and the bit where I thought I was pushing harder showed no difference in erratic than any other part of the run. My HR did go up though, and indeed my HR was a bit higher than I usually manage and fairly constant.
Even with a perfectly evenly paced run I'd expect HR to steadily increase, that's just Cardiovascular Drift.
Technology is a wonderful thing though, I can record all sorts of stats about my speed and pace and HR and breathing and cadence and stride length. And other stuffs. I’ve no idea how to get any sort of control over any other them in spite of real time monitoring. But I can record them all in grate detail 😏
If cadence remains the same the stride length is just proportional to speed. Mo Farah running at sub 3min/km at 180spm means he travels twice as far with each stride as I do when I run at ~6min/km at 180spm.
The actual values for respiration rate, stride length, vertical oscillation, cadence, etc are all well and good but they're mostly secondary to the action of running. The things you can be in control of are speed and cadence and that's about it.
I know some people tend to force themselves to run at a faster cadence, and it doesn't take long to retrain the brain, but I tend to plod at 160spm naturally. I know that as I get faster (which is mostly due to me weighing less) it tends to increase. I was averaging 170spm back when I was lighter and running a sub 25min 5k. I reckon it might even go up towards the magic 180spm if I ever got down to my target weight.
L/R balance can be interesting to see if you're hiding an injury, although it's very easy to see things that aren't there, especially if the ground isn't completely flat. I've got plenty of runs along the Thames Path the L/R balance shifts from 48/52 to 52/48 at the exact point I turn around and run the same route backwards. The seemingly flat path must be angled slightly towards the river. This is the classic example:

My VO2 is steady, but wildly inaccurate. It claims to be 45 at the moment, which predicts a 24:16 5k despite the fastest I've run in the last 6 months is 27:58. I think I know why (it believes I can get near my HR
max whilst running, which I can't since my HR
max was set playing 5-a-side where I can push myself, momentarily, a lot harder) but I can't be arsed to try and work around it. I'm looking forward to the day that the VO2max goes up since it's been 45 for the last 2 years despite my fitness varying hugely.
