A top for a starting platform at one end of a swimming pool has an upper surface,
which is adapted to support both feet of a swimmer in a starting position, and
a lower surface, at which the top is mountable so that the upper surface slants
downwardly and frontwardly. Ribs on the upper surface slant downwardly and laterally
and channels between the ribs slant similarly so as to drain water from the upper
surface. Along each lateral edge, an upper trough and a lower trough facilitate
grasping by one hand of such a swimmer. The upper trough receives water drained
by some of the channels. The front edge is connected to each lateral edge by a
unitary grip, which a swimmer in a different position can grasp with one hand.
