basis. Let's say that I ran it at 56 minutes before, and after some
training, I can run it at 48 minutes. Would that not be an
improvement?
If you get faster by over a minute per mile, even you will be able to work
out that you're getting fitter without using a spreadsheet.

Because that will cause you to train your "carb oxidation system", which will
make Og the low carb caveman god unhappy, and he'll hurl rocks at you from
above. Don't try to run it fast.
Quoted message said:Quoted message said:Races are the best measure of progress. The next best is a particular speed
workout. For example, I can use my 4x1200 track workout, because this is a
workout I often come back to. Training runs are not very useful as a measure
of fitness though.
I agree that races are the best measure of progress, but would
performance on a known run not be a decent measure of progress?
If you're getting faster by minutes per mile, it will be plainly obvious. You
won't need a spreadsheet to work it out.
To detect progress on the order of seconds per mile, you will need a maximal
effort on an accurately measured course. A favourite speed workout on a track
is ideal for this, as is a race.
Quoted message said:My fast speed if 7:52 mpm, measured over one mile. I thought, perhaps
foolishly, that I would run at about 10% slower speed for much
longer.
Depends. Mile times don't reliably predict longer distances. My bests:
1 mile: 4:51
5 mile: 28:27 (5:41 per mile)
I think I could at best do about 5:20 per mile in a good 2 mile race. (I
attempted this year it and couldn't quite do it, but it wasn't a great race.
the 5 mile and 1 mile races were.)
So 10% slowdown only gets me as far as 2 miles.
But there is a lot of variability in 1 mile time for a fixed 5k performance.
This is less true of distances 5k through half marathon, which relaibly
predict each other, because they largely depend on the same thing (aerobic
fitness)
