I suddenly found the perfectly seed for speedrun!
The first is your spawn. The second is cords of the portal in the Neither, if you make portal from spawn's lava pool. The third is cords of the fortress and! Endermen biome! On the same place. If you make the portal in the fortress, you teleported around the cords from fourth picture, and this is really close to the End portal!
