Circus Tryouts is a speedrun introduced in Dino Run SE. It mostly consists of a large downhill slope, and features a very large boulder, allowing the player to practice their Boulder Riding. It is the shortest speedrun in the game, and is very easy to complete.
Circus Tryouts is one of the easiest speedruns to complete on Insane difficulty. It is, however, recommended that the player not attempt to Boulder Ride on Insane difficulty as this will significantly slow them down. Instead, simply run past the giant boulder and you will most likely finish the level well ahead of the Wall of Doom.
