Here is a quick reference of Bolt’s key biographical details.

What condition does Usain Bolt have?

Scoliosis diagnosis

Bolt was diagnosed with scoliosis, a lateral curvature of the spine. In his autobiography, he described the condition and noted it gave him a right leg about half an inch shorter than the left, according to Wikipedia (encyclopedic source). A secondary health source, ScoliCare (chiropractic clinic), reports the spine curves to the right, but this claim has low confidence and is not independently verified.

How scoliosis affected his sprinting

Bolt told ESPN that the scoliosis made him get injured every year in the early part of his career. Yet he also said when he kept his core and back strong, “it didn’t affect me. I was just lucky.” The condition reportedly cut short his 2010 season, according to ScoliCare, though the source is low-confidence.

Other health conditions

There is no credible evidence of any “birth defect” beyond scoliosis. Bolt has never publicly disclosed other chronic conditions. The scoliosis itself is not considered a defect but a common spinal curvature.

Is Usain Bolt still the fastest human?

Current world records

As of 2025 reporting, Bolt still holds the 100m world record at 9.58 seconds and the 200m at 19.19 seconds, confirmed by India Today (news outlet). He also holds the 4×100m relay record of 36.84 seconds.

Retirement and legacy

Bolt retired after the 2017 World Championships, where he placed third in the 100m, opted out of the 200m, and pulled up injured in the 4×100m final, per Wikipedia. No active sprinter has beaten his 100m or 200m world records. The International Athletics Federation recognizes him as the fastest man ever timed.

Has anyone beaten his times?

No. Despite advancements in training and technology, the 9.58 and 19.19 marks remain untouched. Justin Gatlin’s 9.74 and Yohan Blake’s 19.26 are the closest, but still short.

How many children does Usain Bolt have?

Children with Kasi Bennett

Bolt has three children with his long-term partner Kasi Bennett: a daughter born in 2020, and twins (a son and another daughter) born in 2021. The information is confirmed by his public social media posts and interviews.

Names and ages

As of 2025, the eldest daughter is 5, and the twins are 4. Their names have been publicly shared by the family.

Family life

Kasi Bennett described Bolt as “a great father” in a social media post. The family lives in Jamaica, and Bolt frequently shares moments of fatherhood on Instagram.

Bottom line: Three children make Bolt a hands-on dad. For fans curious about his personal life, the takeaway is that he prioritises family over public appearances.

The pattern: Bolt’s family life is a priority, and his public presence reflects that shift.

What happened to Usain Bolt now?

Post-retirement activities

Since retiring in 2017, Bolt has focused on business. He launched a music label, a scooter company, and made promotional appearances for sponsors like Puma. He remains active on Instagram with over 11 million followers.

Business ventures

His 2021 scooter company “Bolt Mobility” faced mixed reviews, but he continues to invest in Jamaican businesses. He also dabbles in music production under the name “Usain Bolt ‘The Bolt’.”

Social media presence

Bolt uses Instagram to share family moments, throwback race clips, and endorsements. He does not post training updates, signalling a full break from athletics.

Who is faster, CR7 or Usain Bolt?

Top speed comparison

Bolt’s top speed during his 100m world record was clocked at 44.72 km/h (27.8 mph). Cristiano Ronaldo’s top speed in a soccer match is around 34 km/h (21 mph), according to sports analytics. The difference is stark: Bolt is nearly 30% faster at peak.

Race results and hypotheticals

The two have never competed in a formal race. In 2017, Ronaldo jokingly challenged Bolt to a sprint, but it never materialised. Over 100m, Bolt would win by a wide margin. Over 5–10 metres, Ronaldo’s acceleration might be competitive, but still slower.

Ronaldo’s sprinting ability

Ronaldo is considered one of the fastest footballers, with a recorded speed of 34 km/h in the 2018 World Cup. Bolt’s speed is in a different category.

Six data points, one pattern: Bolt dominates pure speed; Ronaldo dominates sustained footwork.

The table below compares Bolt and Ronaldo across speed and career metrics.

The implication: Bolt’s speed is unmatched in pure sprinting, while Ronaldo’s agility is tailored to football.

Is Usain Bolt a millionaire?

Net worth estimate

Bolt’s net worth is estimated at $90 million, according to multiple financial outlets. His earnings come from prize money, endorsements (Puma, Gatorade, Nissan), and appearance fees.

Sources of income

During his career, Bolt earned roughly $33 million in prize money. Post-retirement, endorsement deals and his own brand (including a signature shoe) sustain his wealth.

Philanthropy

Bolt has donated to Jamaican charities, including children’s hospitals and education funds. He also sponsors a school in his hometown.

The catch: Wealth after retirement depends on brand management, and Bolt has managed that transition well.
