You'll snap it. Like a twig. Carbon forks, brand name ones that are CPSC/ASTM approved, even heavily built CX alias "gravel" ones are rated for 6" drops. As a matter of standards this is called ASTM "Condition 2"...you need "Condition 3". Which you'll only find on MTB carbon forks, and as such--you'll need MTB geometry due to the much larger axle-crown.

If you're going to be doing parkour on a bike...you want a steel fork.
