The table below summarizes key biographical data for Usain Bolt.

What condition does Usain Bolt have?

Bolt has spoken openly about being diagnosed with mild scoliosis, a lateral curvature of the spine. In interviews he has emphasized that the curve does not affect his running. “It’s not a disability, it’s just a curve in my back. It doesn’t affect me,” he stated (ESPN). Contrary to some online claims, the condition did not require treatment or restrict his training intensity.

Understanding scoliosis

• Scoliosis is a sideways curvature of the spine that most often appears during adolescence.
• Mild cases, like Bolt’s, rarely cause functional limitations.

Medical literature indicates that many elite athletes have managed mild spinal curvatures without performance loss (PubMed (research archive)). The key is that the curvature in Bolt’s case was not severe enough to affect his lung capacity or stride mechanics.

How scoliosis affected Bolt’s training

According to Bolt’s own accounts and his coach’s notes, his training was never modified because of scoliosis. He lifted weights, sprinted at maximum effort, and maintained a standard elite sprinting program. The implication: a mild spinal curve can coexist with world-class performance when managed without alarm.

Is Usain Bolt still the fastest human?

Yes — as of 2025, no one has broken his world records. His 100 m record of 9.58 seconds and 200 m record of 19.19 seconds, both set at the 2009 World Championships in Berlin, remain the fastest officially recorded times in history (World Athletics).

Bolt’s world records: 100 m and 200 m

The table below compares Bolt’s world records with the closest challengers.

Why this matters: Bolt’s records have stood for 16 years, a period longer than most sprint marks last. The sport has not produced a sprinter who can consistently run under 9.65 s or 19.30 s.

Current status of his records

All three world marks remain ratified by World Athletics. The nearest threats — such as Fred Kerley (9.76 s) or Noah Lyles (19.31 s) — are still more than a tenth of a second off Bolt’s best. The pattern: Bolt’s dominance is not just historical; it is still the benchmark of sprinting excellence.

Who is faster, CR7 or Usain Bolt?

Cristiano Ronaldo has been clocked at a top speed of 33.6 km/h (20.9 mph) during matches. Bolt’s top speed in his 9.58 second 100 m race was 44.72 km/h (27.8 mph), measured at the 60–80 m segment (World Athletics). Over 100 m, Bolt is significantly faster; over 30 m from a standing start, Ronaldo may close the gap but still trails. The trade-off: one is a footballer, the other the fastest pure sprinter ever.

Why did Usain Bolt retire so early?

Bolt announced his retirement after the 2017 World Championships in London, where he finished third in the 100 m and then pulled up with a hamstring injury in the 4×100 m relay — his final competitive appearance (Money.com). He cited a gradual loss of motivation and recurring injuries that made it harder to maintain peak form.

Injuries and motivation

In his autobiography and post-retirement interviews, Bolt explained that the daily grind of training became less appealing as he aged. “I just decided it was time to move on,” he said (BBC Sport). At 30, he was still fast, but not as dominant as in his mid-20s. The catch: retiring early preserved his legacy as an undefeated champion over major championships.

What does Usain Bolt do for a living now?

Since leaving track, Bolt has focused on business and brand-building. He launched a series of ventures including Usain Bolt’s Tracks and Records restaurant in Kingston, a premium headphones brand (Chase), and a line of exercise equipment. He also made a short-lived attempt to play professional football, training with Central Coast Mariners in Australia in 2018. His primary income today comes from endorsement renewals — Puma, Sprint, and Advil remain partners (Money.com).

Bolt’s football career attempt

The Mariners signed Bolt to a trial, and he scored two goals in a pre-season friendly. However, a full contract was not offered, and Bolt ended the pursuit. The experience showed that even an elite athlete cannot easily cross over into a sport requiring a completely different skill set.

How many children does Usain Bolt have?

Bolt has three children: a daughter named Olympia Lightning Bolt (born 2020) and twin sons Thunder and Saint (born 2021). Their mother is his long-time partner Kasi Bennett. The couple is engaged but not publicly married (Instagram / personal posts).

Olympia, Thunder, and Saint

• Olympia Lightning Bolt — born 17 May 2020
• Thunder Bolt and Saint Leo Bolt — twins born 4 June 2021

Bolt has described fatherhood as his most rewarding role, often sharing photos of family moments. The naming theme (Olympia, Thunder, Saint) reflects his track persona and personal values.

Who is Usain Bolt’s wife?

Bolt’s partner, Kasi Bennett, is a Jamaican model and entrepreneur. They have been together since 2014 and became engaged in 2019. They are not legally married, but Bennett functions as the family anchor while Bolt travels for business and appearances (Instagram).

Is Usain Bolt a billionaire or a millionaire?

Bolt is a millionaire, not a billionaire. His net worth is widely estimated at $90 million (Investopedia). For context, Forbes ranked him the 23rd-highest-paid athlete in 2017, earning $34.2 million that year, almost entirely from sponsorships (Money.com).

Usain Bolt net worth

The table below breaks down his reported earnings and wealth sources.

What this means: Bolt built his wealth primarily through brand partnerships — only about $2.5 million of his peak annual income came from race winnings and appearance fees (Money.com). His marketability, not his prize money, made him the richest track athlete of all time.

Smoking and lifestyle habits

Bolt has occasionally been photographed with a cigar, leading to speculation. He has clarified: “I am not a smoker. I might have a cigar occasionally” (ESPN). There is no evidence of regular smoking or any performance-relevant substance abuse.

Editor’s note on scoliosis and public perception

Quotes from Usain Bolt

“It’s not a disability, it’s just a curve in my back. It doesn’t affect me.”

— Usain Bolt on his scoliosis (ESPN)

The arc of Bolt’s life — from a small Jamaican village to becoming the most recognized athlete on the planet — is already a modern legend. But the next chapter matters just as much. For sponsors and fans, the question is whether Bolt will remain an active brand ambassador or step into a coaching or mentorship role that shapes the next generation of sprinters. For a 38-year-old father of three, the choice is clear: cash in on a legacy built on nine seconds, or build something slower but more personal.
