20 × 40 m arena · A at the bottom · first the points appear — A, then each touch and each change, in order to C — then the line joins them
Read the points up the side first: where the horse goes, in order, from A to C. Each loop is a half-circle to the wall (blue); the straight between (gold) is where it crosses the centre and changes — a change of bend at Preliminary, a flying change at Masters.
