The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the "quarter-mile"—instead of the 400 m (437.445 yards), though this distance is now obsolete.
Ronald Ray Smith was an American athlete, winner of the gold medal in the 4 × 100 m relay at the 1968 Summer Olympics. He attended San Jose State College during the "Speed City" era, coached by Lloyd (Bud) Winter and graduating in sociology.
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each. The first runners must begin in the same stagger as for the individual 400 m race. Each runner carries a relay baton. Before 2018, the baton had to be passed within a 20 m changeover box, preceded by a 10-metre acceleration zone. With a rule change effective November 1, 2017, that zone was modified to include the acceleration zone as part of the passing zone, making the entire zone 30 metres in length. The outgoing runner cannot touch the baton until it has entered the zone, and the incoming runner cannot touch it after it has left the zone. The zone is usually marked in yellow, frequently using lines, triangles or chevrons. While the rule book specifies the exact positioning of the marks, the colours and style are only "recommended". While most legacy tracks will still have the older markings, the rule change still uses existing marks. Not all governing body jurisdictions have adopted the rule change.
60 metres, or 60-meter dash, is a sprint event in track and field. It is a championship event for indoor championships, normally dominated by the best outdoor 100 metres runners. At indoor events, the 60 metres is run on lanes set out in the middle of the 'field', as is the hurdles event over the same distance, thus avoiding some of the effects of the banked track encircling the venue, upon which other track events in indoor events are run. At outdoor venues it is a rare distance, at least for senior athletes. The format of the event is similar to other sprint distances. The sprinters follow three initial instructions: 'on your marks', instructing them to take up position in the starting blocks; 'set', instructing them to adopt a more efficient starting posture, which also isometrically preloads their muscles. This will enable them to start faster. The final instruction is the firing of the starter's pistol. Upon hearing this the sprinters stride forwards from the blocks.
