Early on, Kalle Berglund ended up second at the back of the group in his test heat of 1500 meters at the Olympics in Tokyo.

With 800 meters left, Kalle Berglund was forced to let go.

A powerless Berglund ended up further and further behind in the distance from the other runners and when the bell rang for the last lap, Berglund was far from the group.

Twelve in goal

In the finish, Kalle Berglund was the twelfth runner;

he had needed to be in the top six or had a good time to advance to the semifinals.

Berglund ran in at 3.49.43, more than 13 seconds behind the winner Jake Heyward, Great Britain, who won in 3.36.14.

"Overtraining and mental illness"

Kalle Berglund came to the Olympics in Tokyo after a difficult season, when he broke three of four races.

- The body has not functioned throughout the summer.

I hoped and thought it could turn around, but it did not.

It is due to a combination of overtraining and mental illness.

I have not felt well this year.

The mental also affects the physical, says Kalle Berglund in Discovery + broadcast.

Has the Swedish record

Kalle Berglund holds the Swedish record of 1500 m - 3.37.70 from the World Athletics Championships in Doha 2019.

Four in Berglund's heat, and thus on to the semifinals, was the Norwegian running sensation Jakob Ingebrigtsen, 20.

The Norwegian ran at 3.36.49.
