This position is at the intersection of the 800m break line and the inner line for the 2000m and 10,000m. The IAAF 400m Standard Track Marking Plan shows the starting positions for the first athletes in each lane for the 4 × 400m relay competitions. These are the positions that race officials use to determine who goes first and who goes last on each leg of the relay. The plan also indicates where to place the handoff between legs. The best option is for all four members of the relay team to start at the same time from these positions. But if this isn't possible because of traffic delays or some other reason, then a handoff between any two lanes will do as long as it's done before the gun goes off. After the first handoff, the remaining two runners should stay near the inside lines until the second handoff, when they too can move outside. In conclusion, the starting positions for the 400m relay are at the intersection of the 800m break line and the inner line for the 2000m and 10,000m.
