At first, the Olympic Games contained one event: the stadion race, a short sprint measuring between 180 and 240 metres, or the length of the stadium.

The diaulos, or two-stade race, was introduced in 724 BC, during the 14th Olympic games. The race was a single lap of the stadium, approximately 400 metres.

A third foot race, the dolichos was introduced in 720 BC. The length of the race was 18-24 laps, or about three miles (5 km). The event was run similarly to modern marathons-the runners would begin and end their event in the stadium proper, but the race course would wind its way through the Olympic grounds.

The last running event added to the Olympic program was the hoplitodromos, introduced in 520 BC and traditionally run as the last race of the Olympic Games. The runners would run either a single or double diaulos (approximately 400 or 800 yards) in full or partial armour, carrying a shield.

Over the years, more events were added:boxing, wrestling, pankration (regulated full-contact fighting), chariot racing, as well as a pentathlon (consisting of wrestling, stadion, long jump, javelin and discus).

Handball (also known as team handball, Olympic handball, European team handball, European handball, or Borden ball) is a team sport in which two teams of seven players each (six outfield players and a goalkeeper on each team) pass a ball to throw it into the goal of the other team. A standard match consists of two periods of 30 minutes, and the team which scores the most goals wins.

Modern handball is usually played indoors, but outdoor variants exist in the forms of field handballand Czech handball (which were more common in the past) and beach handball (also called sandball).

The game is quite fast and includes body contact, as the defenders try to stop the attackers from approaching the goal. Contact is allowed only when the defensive player is completely in front of the offensive player; i.e., between the offensive player and the goal. Any contact from the side or especially from behind is considered dangerous and is usually met with penalties. When a defender successfully stops an attacking player (who loses the ball over a line), the play is stopped and restarted by the attacking team from the spot of the infraction or on the 9-metre line. Unlike in basketball, where players are allowed to commit only 5 fouls in a game, handball players are allowed an unlimited number of faults, which are considered good defence and disruptive to the attacking team's rhythm. Certain elements of the game are reminiscent of rugby: for instance, the degree of force that defence may use to stop the attacker with the ball, together with the lack of protections and helmets.

Goals are scored quite frequently; usually both teams score at least 20 goals each, and it is not uncommon for both teams to score more than 30 goals. This was not true in the earliest history of the game, when the scores were lower. But, as offensive play has improved since the late 1980s, particularly the use of counter-attacks (fast breaks) after a failed attack from the other team, goal-scoring has increased. hope this helped.
