A starting block for swimming equipped with a single curved surface to facilitate track starts while reducing the trip hazard of such a surface. This allows for safer mounting from rear and side steps and removes undesirable gaps in the top surface of the starting block. A pliable embodiment of said curved surface can modify the distance of the curvature from the leading edge of the starting block to adapt to different swimmer needs. An apparatus to obtain said distance for a given swimmer from a meet management system to modify the pliable embodiment for quick change during time-constrained events such as meets.
