Trying to get a sub 2:10 800

Jog it around tempo pace

I think you'll reach your goal in your next race simply because you've recently run the race and your 400m speed is ample.

As an aside, you need to work on your mile time - it's quite slow for your 400m speed.

Based off your 400m time, your 800 is at 91%, the only way to go up from there is with endurance/stamina which based off your current mile time, you lack. Get good thresholds runs in, both long and short, and make sure to do mile repeats. Those workouts in combo with your speed will get your 800m and 1600m time down.
Good luck!

Bro if you’re a male 2:10 should be nothing, just tough it out.

jk, if you absolutely are set on doing anything you can to hit this time in tbe next 10 days, do speed endurance work. Your general endurance will not improve over the next 10 days, best you can do is to sharpen up and get pace work in at goal pace

2x4x200m 30 secs between reps 8 minutes between sets. Aim to hit them in 32.

You definitely need some endurance work. Do some longer track reps at a slower pace that your 800m PR. Something like 6x600m at 3200m pace or mile pace + 25 seconds (about 2:10 per rep), with 2-3 min of rest. This should help speed up your mile time too.

Run your next 800m race like you previously did, first lap in 63 seconds, and then keep up a lot of effort with 500m to go. It will hurt a bit, but that's just how the 800 is. Good luck!
