The Field Events are evenly distributed over the arena to avoid congestion and to satisfy the needs of the spectators. This layout avoids undue disruption of events by ceremonies and counterbalances the concentration of interest in the finish area.
The layout is. of course, flexible. Local climatic conditions particularly wind conditions and the effects of the rays of the sun on jumpers / vaulters must be considered.
Fiqures 2.5b and 2.5c show the slope of the northern segment (radial and lean- to slopes),Figures 2.5d and 2.5e the slope of the southern segment (radial and lean-to slopes).
