The first runners must begin in the same stagger as for the individual 400 m race.  A relay baton is carried by each runner and must be passed within a 20 m changeover box (usually marked by yellow lines) which extends 10 m on either side of each 100 m mark of the race.  Another line is marked 10 m farther back, marking the earliest point at which the outgoing runner may begin (giving up to 10 m of acceleration before entering the passing zone).
