摘要
A running surface for a common exercise treadmill has an endless belt made of a rubber like material leaving a smooth finish to its upper and lower surfaces. At least one line of spaced apart holes penetrate the belt along its entire length. The holes enable fastening elements to affix generally circular rods to the upper surface to engage fastening eyelets by means of the fastening elements which are installed into at least one strengthening endless belt positioned below and urging against the lower extremity of the endless belt. The generally circular rods have prefabricated objects such as simulated cobblestones of various sizes and configurations in immediate adjacency to the upper extremity of the endless belt.
