A light load for a hieracosphinx is up to 350 pounds; a medium load, 351-700 pounds; and a heavy load, 701-1,050 pounds. A typical hieracosphinx is just short of 9 feet long and weighs 600 pounds. Hieracosphinxes detest bearing a rider into battle, thus increasing the DCs of any combat-related Ride checks by +5.
