I have made a parkour map of medium difficulty (In my opinion) on the Minevast Creative server. It is called Holy Walls, and the map is made mostly of quartz blocks. You can use /warp HolyWalls to get there, Crush set the warp for me. There are 52 jumps with 5 checkpoints. No WorldEdit was used. The username of the map creator (me) is happyheart.
Here are some screenshots:
