Kilian Jornet drops out of 24-hour running world record attempt, feeling dizzy and seeking medical evaluation
- The mountain running superstar swapped trails for tracks in an attempt to beat Yainnis Kouros’ 303.506km record set in 1985
- Jornet completes 134km before doctors advise him to seek help for dizziness
Kilian Jornet has dropped out of his 24-hour running record due to dizziness. The famous mountain runner did continuous loops of a track in Norway in an attempt to set a new distance covered in a day.
Jornet had run 134km after 337 laps. The record he was going for is Yainnis Kouros’s 303.506km set in 1997.
The Salomon team shared an Instagram story, firstly showing Jornet receiving physio on his knee, then announcing he dropped out and finally explaining: “Kilian was feeling dizzy, so he received medical attention on the track. Although he was feeling better, the medical professionals decided it was best for him to go for further evaluation.”
Kouros, from Greece, is considered the best road ultra runner of all time. His 24-hour record has stood for an incredible amount of time. He also holds the 48-hour record on a track (473km), set in 1996 and the six-day record (1,036km) set in 2005.

Jornet is no stranger to turning over historical records. He set the record on the 106km Bob Graham Round in England in 2018, beating Billy Bland’s time that had stood for 36 years.
