Abstract

A lightweight runners starting block assembly with adjustable positions for the foot blocks and adjustable angles for the foot plates is disclosed. The position of the foot blocks can be adjusted by selecting from a series of holes in the central tie bar. The tilt angles of the foot plates can be adjusted by selecting from one of several notches in the brace arms. The foot blocks can be easily removed from the central tie bar and folded flat so that the three parts can be stored in a small bag for convenient portability.
