Indoor altitude factor: NCAA publishes altitude-conversion tables for performances at high-altitude venues (5,000+ feet); marks may be wind-noted but timing is FAT; 200m vs 400m oval: NCAA accepts marks from both for qualifying, with conversion factors published

Lane assignments and lane-line rules apply with adjusted radius for banked turns; Stagger lines accommodate banked-track geometry; Stepping inside the lane on a banked turn carries DQ if it impedes another runner

Sprints: 60m, 200m, 400m; Middle/long distance: 800m, Mile (1609m), 3000m, 5000m; Hurdles: 60m hurdles

Throwing implements: shot put, weight throw (replaces hammer indoors); same NCAA-approved spec as outdoor; Indoor-specific: weight throw — men 35 lb (15.88 kg) / women 20 lb (9.07 kg) — replaces the hammer for indoor competition; Hurdles: men's 60m hurdles 1.067m / women's 60m hurdles 0.838m

200-meter oval track (smaller than outdoor 400m), 4-6 lanes typical; Track may be banked (curves rise toward the outer edge to allow faster running) or flat; Sprint and hurdle straightaway: separate 60m straight track or use of the oval straight

Officials: meet referee, starters, recall starters, finish judges, lap counters, field-event judges, implement inspectors, wind-gauge operators (when used); FAT (Fully Automatic Timing) required at championship; NCAA D1 Indoor Championship: top 16 individual + top 8 relays advance per event from ...

Sprints: 60m, 200m, 400m; Middle/long distance: 800m, Mile (1609m), 3000m, 5000m; Hurdles: 60m hurdles

Individual events: lowest time wins (FAT to 0.01 sec); jumps/throws: longest mark wins; combined events: highest score per published World Athletics tables; NCAA team scoring: 10-8-6-5-4-3-2-1 (top 8 score); relays score double; Tiebreakers: photo finish for ties; second-best mark for tied jump/t...

False start: zero-tolerance DQ (consistent with World Athletics 2009-onward); Lane infringement: stepping inside lane line on a curve, impeding another runner = DQ; Relay exchange violation: outside the 20m exchange zone = relay DQ

Indoor venue safety: ceiling clearance for pole vault and high jump verified; throwing cages required for weight throw; sector marshals positioned. Pole-vault and high-jump landing-mat dimensions and minimum thickness per NCAA spec.
