800 metres
800 m is a common track running
event. It is the short common middle
distance. The 800 meters 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.
The race is widely considered to be the most difficult mental
challenge in track and field. It requires both sprinting speed as
well as the physical endurance to last two laps, and thus combines
the most challenging aspects of both into a single race. The
closest races to the 800 m are substantially different, with the
400 m being a sprint
with almost nonstop speed, while the 1500 m (or
1600/mile) is a more tactical distance event.
Tactics
In modern 800 m races, runners start from staggered positions on
the track and must remain in their respective lanes for the first
100 m of the race. After the first 100 m, competitors may break for
the inside, as long as they do not deliberately obstruct or push
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 in lane one but not leading the race must also be careful
to avoid becoming boxed in by other runners, as this eliminates the
crucial ability to completely control one's own pace. Running in
last place is also not recommended, as there may be too much ground
to make up when the final sprint for the finish starts. However, it
can be sensible for an athlete to remain at the back of the field
if the pace at the front is far too fast, provided that the athlete
in question does not leave too much ground to make up. This was
illustrated by Kelly Holmes at the
Athens Olympics,
who stayed to the rear of the field until the last 300 m before
making a decisive move. A more unorthodox tactical move came from
John Woodruff who,
in the 1936 Olympics, was
boxed in by runners early in the race. He slowed almost to a
complete stop, let the runners pass, and then took the third lane
to come from behind and take the victory.
In top class races, the lane start usually ensures a brisk pace
for the first 200 m. Occasionally, no one will be happy to lead,
and the field will bunch for the remainder of the first lap. This
usually leads to an abnormally slow first 400 m, and allows the
runners extra energy for a hard sprint on the second lap, favouring
the sprint type 800 m runner. 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.
This favors the endurance or distance type 800 m runner. However,
the occasional 800 m runner is able to produce a world-class 800
with even laps, or even negative splits.
Records
800 m runners are often fast enough to run in the 4x400 m relay but
only Alberto
Juantorena and Jarmila
Kratochvilova have won major international titles at 400 m and
800 m. Competing successfully at 800 m and 1500 m is more
common.
