A few specifics.
Event categories.
- Sprints: 100m, 200m, 400m. Hurdles: 100m (girls), 110m (boys), 300m or 400m hurdles.
- Distance: 800m, 1500m or mile, 3200m, plus 1500/3000m steeplechase.
- Relays: 4x100m, 4x200m, 4x400m, 4x800m, distance medley relay.
- Jumps: long jump, triple jump, high jump, pole vault.
- Throws: shot put, discus, javelin, sometimes hammer at the elite level.
Spikes matter. Sprint spikes have shorter, sharper pins. Distance spikes are lighter with shorter pins. Jumping spikes have specific configurations. Throwing shoes are flat-bottomed. The wrong shoe slows the kid down or risks injury.
Heat structure. In bigger meets, sprints are run in heats; the fastest times across all heats determine final placement. Some events have prelims and finals.
Field events have rotations. Most field events give each athlete three attempts in prelims; top 8 or 9 advance to finals for three more.
Wind matters. Sprints, jumps, and hurdles can be wind-aided. A wind reading of +2.0 m/s or more makes the result “wind-aided”, still valid for placing but doesn’t count for record purposes.
