ABSTRACT:
A long jump marking board that discloses the point of take-off of a long jump in athletic competition or practice comprising an array of elongate marking elements pivotally mounted to a base. The elements are closely spaced, parallel to each other, and transverse to the direction of the jump. Prior to use, the elements are situated in a first position extending substantially upward from the base. When a jump is made, using the marking board as a take-off point, an athlete's foot will contact a number of the elements and cause them to be pivoted to a second position angularly disposed to the base. The pivoted elements remain in the second position illustrating the point of foot contact and the take-off point of the jump. An accurate measurement may then be taken from the take-off point to the landing point. A reset mechanism is provided to reset all pivoted members to their original upright position.
