Can I Make An Infinite Parkour Map in Minecraft?

I work on the idea of creating parkour that continues on forever in Minecraft. This works by procedurally generating the next jump for the parkour as you land at the previous jump. This is done through a complicated command block system, where a dispenser filled with shulker boxes is used as a randomizer for where the next jump is placed. However, this process is slow, I wonder if there's a better way? (There is, tune in next time for that.) Have any suggestions? Come on over to the Discord!   / discord  

I use a Redcoder in this video that isn't mine, the person who created that can be found here, give them a watch!:
