Reading a Results Sheet: Times, Marks and Wind Readings

Why some brilliant performances come with an asterisk, and what the small print actually means.

Athletics results carry more annotation than any other sport’s, and each mark exists to make performances comparable across conditions.

Wind readings

In sprints and horizontal jumps, a tailwind above a set limit makes a performance ineligible for records. The result still stands as a competition placing — it simply cannot be compared with still-air marks.

Timing systems

Hand-timed and electronically timed performances are recorded differently, because a human reaction to a starting gun adds a measurable lag.

Altitude

Thinner air helps sprinters and hurts distance runners. Results from high-altitude venues are frequently flagged for that reason.

Why any of it matters

Because athletics compares athletes who never met, across decades. Every annotation exists to keep that comparison honest.
