About Laviai Nielsen
Early Life and Inspiration
Laviai grew up in Leytonstone, East London. Her mother is from Egypt and Sudan, and her father is Danish. When she was 16, Laviai had a special experience. She was a bag carrier for British athlete Jessica Ennis at the 2012 London Olympics. This moment really inspired her to become an athlete.
She remembered, "I stood behind Jessica Ennis. When she came out, the crowd cheering was the loudest thing I've heard in my life. I thought, 'I want that'."
In 2017, Laviai was taking a break from her geography degree at King's College London. She is also an Athlete Ambassador for Right To Play, a charity that uses sport to help children.
Starting Her Athletics Journey
Laviai first started as a middle-distance runner. But in 2013, she and her twin sister were encouraged to try the 400 metres. Laviai quickly improved her 400m personal best time. She got two seconds faster in just two months. By the next season, she was four seconds faster!

Her big year was 2015. She won gold in the 400 metres at the European Athletics Junior Championships in Sweden. She also ran the last part of the winning 4x400 metres relay team. Her sister Lina ran the second part of that race. Laviai also set a new personal best time of 52.25 seconds. This was one of the fastest times ever for a British junior runner.

Laviai's Health Journey
Living with Multiple Sclerosis
In August 2022, Laviai shared that she was diagnosed with multiple sclerosis (MS) in the summer of 2021. MS is a condition that affects the brain and spinal cord. Her twin sister, Lina, had shared her own MS diagnosis two weeks earlier. Lina was diagnosed in 2013 when she was 17.
Because MS can sometimes run in families, Laviai was tested after Lina's diagnosis. Both Laviai and Lina received support from their friend, Paralympic champion Kadeena Cox. Kadeena also has MS and started competing in Paralympic sports after her diagnosis. Even with their MS diagnoses, Laviai and Lina continue to compete in Olympic athletics.
