[01]What Is Seeding in Track?

Seeding, explained

What seeding is

Seeding ranks entrants by their submitted marks and uses that order to build the heats and assign lanes. The goal is fairness: the fastest athletes should not all land in the same heat or the worst lanes.

How heats are seeded

The top seeds are distributed across separate heats so each heat has a contender, and within the final or a fast heat, the best seeds get the middle lanes. The middle lanes are favored because the curve is gentler and you can see your rivals.

Why it matters

Seeding affects who you race and where you run. A good seed earns a better lane and a faster heat, which can matter for time qualifying, so accurate entry marks are worth getting right.

Top seeds spread across the heats

Seeding ranks entrants by mark, then spreads the fastest across heats and into the best lanes rather than stacking them.
