10-second barrier
the physical/psychological barrier of completing the 100 m sprint in under 10 seconds
The 10-second barrier is the physical and psychological barrier of completing the 100-meter sprint in under ten seconds. The achievement is traditionally regarded as the hallmark of a world-class male sprinter. Its significance has become less important since the late 1990s, as an increasing number of runners have surpassed the ten seconds mark. The current men's world record holder is Usain Bolt, who ran a 9.58 seconds at the 2009 IAAF World Championship final.
Jim Hines was the first person to ever officially run the 100 metres under 10 seconds at the 1968 Mexico City Olympics. The fastest non-winning sub-10 performance was by Tyson Gay who clocked 9.71 in 2009 as a runner-up. The only quadragenarian to have run a sub-10 is Kim Collins who ran his personal best time of 9.93 in 2016 at 40 years old, earning him the nickname Ageless Wonder. Justin Gatlin chronologically held the longest streak of sub-10 performances in history, having a sub-10 career in a time-span of nearly 18 years, from his first sub-10 clocking in 2003, to the final one in 2021. In 2025, Akani Simbine became the first athlete in history to run the 100 metres in under 10 seconds in eleven consecutive seasons—a streak he extended to twelve seasons by 2026. That surpassed the previous record of ten, held by Bolt.
This brief starts where responsible research should: with the source description of “10-second barrier” as the physical/psychological barrier of completing the 100 m sprint in under 10 seconds. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as the physical/psychological barrier of completing the 100 m sprint in under 10 seconds. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q163866. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009, 1968, 2016 and 2003.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
