Why heats exist
A track has a limited number of lanes, usually eight, so when more than eight athletes enter a sprint, the field is split into multiple heats. Each heat is a separate race, run to decide who moves on.
A heat is one of several preliminary races run when too many athletes enter an event to race at once. Heats narrow a large field down to a final. Here is what a heat is and how you advance out of one.
A track has a limited number of lanes, usually eight, so when more than eight athletes enter a sprint, the field is split into multiple heats. Each heat is a separate race, run to decide who moves on.
You advance from a heat in one of two ways: by place, the top finishers in each heat, or by time, the next-fastest across all heats, called time qualifiers. The exact rule is set by the meet.
Distance races often run in sections instead of heats, scored on time across all of them. Athletes are seeded into heats by their entry marks, so the fastest are spread out rather than stacked in one race.
Advancing from a heat often comes down to a tenth or two. Film a race, the AI grades the technique most likely to drop your time, so you give yourself the margin to qualify.
