800m

The 800m is run over two laps of the track and has always been an Olympic event. It was included in the first women's track programme in 1928, but suspended until 1960 because of shock at the exhaustion it caused the competitors. By contrast, without today's training regimes, male competitors of the day were expected to run themselves to exhaustion in competition. In the last 11 Olympic Games, athletes from 10 different countries have won the mens 800m title.

Tactics

In a modern competition, the first 100m is run in lanes, after which competitors may break for the inside without deliberately obstructing or pushing another competitor. Running flat out for this distance is impossible and tactics can be a factor in reaching the finish line first. Running in the lead is often considered a disadvantage as trailing runners can choose when to accelerate past the leader, and the effect of wind resistance. Runners not in first place on the inside can find themselves boxed if other runners start to overtake them. Running in last place is not recommended as there may be too much ground to make up when the final sprint for the finish starts.

In top class races, the lane start usually ensures a brisk pace for the first 200m. Occasionally, no one will be happy to lead and the field will bunch for the remainder of the first lap leaving a sprint on the second lap. More often, one runner will ensure a fast first lap and the winner will be the one who slows least on the second lap, despite the appearance of sprinting at the finish. However, the occasional 800-meter runner is able to produce a world-class 800 with even laps, or even negative splits.
