4x100 BLIND PASS
Relay exchange zones
In the 4x100-meter relay and 4x200-meter relay, and other relays with legs of 200 meters or less, each exchange zone will be 30 meters long. All exchange zones for races in excess of 200 meters will remain at 20 meters.
The beginning of the 30 meter zone would already be marked at the spot where the acceleration (“FLY”) zone began under the old rule. On tracks where relay exchanges are denoted with inward triangles the width of a lane, it is a small inward pointing triangle marked in the center of the lane ten meters before the ”old” exchange zone. Tape or a painted line is allowed to make it more visible if need be. If athletes are standing forward of the little triangles, they are in the 30 meter zone.
