Inspired by this question, what is the farthest distance you can move on one turn?
Assuming you're a Wood Elf monk at level 20, you get 35 base + 30 feet Unarmored Movement, adding the Mobile feat and a casting of Longstrider from a friendly character, you're at 85 movement. If you're also under the effect of a Haste potion or spell, that increases to 170. You can now use your regular action, your extra action, your movement and your bonus action to go four times 170 feat, i.e. 680 feet.
As an Aarakocra, you would have a base flying speed of 50 - if the monk's, the Mobile feat's and Longstrider's movement increases add to this speed (and not your 25 walking speed), you would have 100 base, i.e. you could go 100*2*4=800 feet.
If those movement increases also add to Fly's flying speed (60), you would have 110*2*4 = 880 feet.
Is that the farthest you could possibly go in one round? Or is a higher speed possible using some kind of spell, potion or other thing that I'm unaware of?
For the purposes of this question, ignore the 300 flying speed you could get from Wind Walk, which takes 1 minute to transform (and your DM might rule that you can't dash in transformed form, or wouldn't be affected by haste).
