The name doesn't have to be at the parkour, if we think about it I can say a couple without: Easys; Cake, Stone Tower, Mario Block, Creeper, Ghast... Those were only easys, but every single one of them has same thing... They don't even have a starting place! This is where I get to my point.
All map creators, you do not have to make a starting place to your parkour, you can just start the parkour and it's fine! Don't try to do a good starting place and fail if you think that you can be without a starting place completely!
