Answer in brief
The fastest person in history is Jamaican sprinter Usain Bolt. His world records of 9.58 seconds for 100 metres and 19.19 seconds for 200 metres, set in 2009, remain the top verified performances on record. Bolt also anchored Jamaica’s 4x100m relay world record at 36.84 seconds in 2012. No other human has surpassed these marks in official, measured competitions.
How we define and measure fastest human speed
“Fastest person in history” is determined by the lowest official time over a measured distance in recognized competition. Times must meet strict criteria:
- IAAF/F World Athletics rules
- legal wind readings (≤+2.0 m/s for record eligibility)
- proper start and timing protocols using photo-finish and electronic timing to hundredths of a second
- doping‑free status at the time of performance
Without these conditions, a run may be fast but is not eligible for world record status. Wind-aided performances can be recognized as meeting the conditions for record eligibility but are marked as assisted, which is important for historical comparisons.
Why records matter and how they are verified
World records are not just fast times; they are legal performances documented by official agencies, witnessed, and ratified. Technical checks include wind gauges, certification of tracks and surfaces, and validation of timing systems. Only records ratified by the sport’s governing body are considered authoritative for historical ranking. This protects the integrity of the title fastest person in history and ensures consistency across eras.
The 100 metres record holder
Usain Bolt set the 100m world record at the 2009 World Championships in Berlin with a time of 9.58 seconds. This performance remains the fastest human powered sprint over 100 metres in history. It was measured with official timing, met wind-legal criteria, and has not been surpassed in any ratified event.
Key context around the 100m record
- Location: Berlin, Germany
- Date: 16 August 2009
- Wind: +0.9 m/s (fully legal, not wind-assisted)
- Timing: Fully automatic electronic timing to hundredths of a second
- Status: Still ratified as the world record by World Athletics
The 200 metres record holder
Bolt’s 200m world record of 19.19 seconds, also set in Berlin on 20 August 2009, is the fastest 200 metres ever run. The performance is widely regarded as one of the greatest sporting feats because it combines elite top‑speed with exceptional endurance over twice the distance.
Why the 200m record stands out
- Race structure: 200m includes a curve entry, where technique and speed must adapt.
- Wind: +0.6 m/s, well within legal limits.
- Timing and track: high‑quality electronics and surface conditions verified by IAAF.
- No ratified 200m performance has been faster in history.
Relay performance: 4x100 metres
Although team performances involve multiple runners, the fastest 4x100m relay marks are significant. At the 2012 London Olympics, Jamaica’s quartet of Nesta Carter, Michael Frater, Yohan Blake, and Usain Bolt ran a time of 36.84 seconds, a ratified world record. Bolt’s split anchoring leg helped set this mark, contributing to the perception of him as the fastest person in history over the anchor leg and in combined team achievements.

How top speed is measured in practice
Official timing for elite sprinting uses systems that record to one hundredth of a second across the line. Multiple cameras, sensors at the start, and strict control of conditions ensure accuracy. Wind is measured at 10‑minute intervals and averaged for the 2‑second measurement window crossing the timing beam. Only when the average wind does not exceed +2.0 m/s is the performance eligible to be a record for the fastest person in history, because wind can artificially increase speed.
Notable performances and common questions
- Usain Bolt’s 9.58s 100m and 19.19s 200m are ratified as world records and remain the fastest legal performances.
- Some races in training or informal timing may show fast numbers, but they are not ratified by World Athletics.
- Technological advances in track surfaces, spikes, and timing have improved precision, but they do not erase the requirement for legal wind and proper procedure.
- Wind‑aided performances are noted separately; they are fast but marked as assisted when published.
Comparisons across distances
Because 100m and 200m are different race profiles, direct speed comparisons require context. The table below summarises the current ratified world records that define the fastest person in history for each event.
| Event | Record | Athlete | Date | Location | Wind |
|---|---|---|---|---|---|
| 100 metres | 9.58 s | Usain Bolt (JAM) | 16 Aug 2009 | Berlin, Germany | +0.9 m/s |
| 200 metres | 19.19 s | Usain Bolt (JAM) | 20 Aug 2009 | Berlin, Germany | +0.6 m/s |
| 4x100 metres relay | 36.84 s (team) | Jamaica (Carter, Frater, Blake, Bolt) | 11 Aug 2012 | London, UK | N/A |
Frequently asked questions
- Has anyone run faster than Usain Bolt? No. No ratified performance has surpassed Bolt’s 9.58s 100m or 19.19s 200m in official competition.
- Are there faster times in training or unofficial events? There may be faster hand-timed or informal readings, but they are not ratified by World Athletics and do not meet official record criteria.
- What is the role of wind in these records? Records require wind ≤+2.0 m/s. Wind-aided runs are noted separately and are not eligible to be the ratified fastest person in history for record purposes.
- Will future athletes break these records? Records can and do fall, but as of now Bolt’s performances remain the verified fastest ever.
Why Bolt is considered the fastest person in history
Usain Bolt combines top-end speed, consistency, and longevity in a way no other sprinter has matched. His world records in the 100m and 200m stand as the best ratified performances under official conditions. While training sessions and technology evolve, the benchmark of the fastest person in history remains tied to these verified, rule-compliant marks that define the peak of human sprint performance.
