Why is 1000m interval pace the same as 400m interval pace on Jack Daniels VDOT calculator?
Why run the 400m at the same pace as the 1000m? I thought shorter intervals were meant to be ran faster?

2nd edition? I think there's a typo on one of the pages.

read the book instead of looking at random pages. jesus.
I haven't read the book I just use the online calculator at runbayou. Is the calculator wrong?
Well if it's "interval pace," then it does not change for longer or shorter repeats.
Well that's stupid if I can run 1km in 3:44 I can easily run 400m in 1:30 it's the same pace but less distance so what's the benefit

You're stupid because you are attempting to use tables that you don't understand. VDOT tables are pa es that are relative to VDOT, when is the pace of maximum oxygen uptake.

You're right. Vdot IS stupid.
If your are following Daniels' plan and he wants you to run faster, he'd use a different name (Rep pace or 'R'-pace)
As far as what the benefit is, you usually cannot handle 1000 repeats 5K pace early on in training. Familiarizing yourself with the pace in shorter lengths 8-12 weeks out from a goal race is the plan.

What you do not understand is that intervals for best efficiency are run at your vVO2max that is at your maximal oxygen uptake pace. If you run the intervals faster than vVO2max pace, you are just producing more lactic acid and that acid is burning your aerobic enzymes in mitochondria. So you might suffer a lot of pain by running faster intervals but you might actually do more harm than good this way if not ready for the pace.
So 400, 800, 1000, 1200 or even 1600 meter intervals must be run at the same pace. The only difference is the recovery time which must be kept 1:1. So after 400 you will usually have just ~60 sec recovery but after 1000s you will have ~3:00.
1:1 rest is pretty generous.
One of the ways I use intervals is to keep rest at 70-80% for longer intervals and more like 50% for shorter intervals. This has worked really well for me. I think it fits better with Daniels' theory.

Can you easily do 20 x 400 at that pace?
Read the book if you want to understand his training rather than trying to infer everything from one table you found online.

Nonsense. If you´re running vVo2max pace for shorter than 3 minutes the recovery must be kept short, otherwise the oxygen consumption drops too much. You obviously haven´t read Daniels, either.
