Athletics is a sport, comprising a group of athletic events or disciplines, each of which involves either running, walking, throwing or jumping. It is divided into: track, field. Track Events Men and women do not compete against each other, although they may sometimes run in the same races due to time constraints at high school meets. Women generally run the same distances as men although hurdles and steeplechase barriers are lower and the weights of the shot, discus, javelin and hammer are less. o Track events - running events conducted on a 400 m track. o Sprints: events up to and including 400 m. Common events are 60 m (indoors only), 100 m, 200 m, 300 m and 400 m. o Middle distance: events from 800 m to 3000 m, 800 m, 1500 m, mile and 3000 m o Steeplechase - a race (usually 3000 m) in which runners must negotiate barriers and water jumps. o Long distance: runs 5000 m or over. Common events are 5000 m and 10000 m. Less common are 1, 6, 12, 24 hour races. o Hurdling: 110 m high hurdles (100 m for women) and 400 m intermediate hurdles (300 m in some high schools). o Relays: 4 x 100 m relay, 4 x 400 m relay, 4 x 200 m relay, 4 x 800 m relay, 4 x 1 Mile relay, etc. Each runner must hand off the baton to the next runner within a certain zone, usually marked by triangles on the track. o Road running: conducted on open roads, but often finishing on the track. Common events are over 5 km, 10 km, half-marathon and marathon. The marathon is the only common road-racing distance run in major international athletics championships such as the Olympics. o Race walking: usually conducted on open roads, but is also a typical event in high school meets. Common events are 10 km, 20 km and 50 km. o Field events o Throwing events + Shot put an athletics event involving "putting" (throwing in a pushing motion) a heavy metal ball (called the shot) as far as possible. + Hammer throw is an athletic throwing event where the object is to throw a heavy metal ball attached to a wire and handle. + Javelin throw is an athletics throwing event where the object to be thrown is the javelin, a spear-like object made of metal, fiberglass and, in some cases, carbon fiber. + Discus throw is an athletic throwing event competition.
