This is the world. A few things about it. If you use the Openvr advanced settings manual/auto redirected walking and change your avatar it'll bring you towards the center of your playspace. So don't change your avatar while on the trail. Also use an avatar that is roughly scaled to your real height or you might be walking a lot more than 4km. I did fix the checkpoints, and added a few more things on the trail.
