Centripetal Force is the force that allows the horse to take a turn, it does NOT push a horse out. Inertia keeps the horse wanting to move in a straight line. So blame it on the horse's mass, or intertia, not Centripetal Force.
Centripetal force, in this case is supplied, by friction between the horses hoof and the turf. If a horse tried to take a turn on a frictionless surface (ex.something like ice) it would be unable to do so, no turning without friction in this case.

And I thank you. A public service announcement.

its jerrys kidds..
