[1] A member of the Swedish track and field team at the 2015 IAAF World Championships and at the 2016 Summer Olympics, he launched his personal best throw of 66.03 m at a national track and field meet in Helsingborg nearly a month before the Games.

[4] Härstedt competed for Sweden, along with his fellow countryman Daniel Ståhl, in the men's discus throw at the 2016 Summer Olympics in Rio de Janeiro.

Nearly a month before his maiden Games, he successfully nailed the IAAF Olympic entry standard (65.00) by over a single metre with a personal best of 66.03 at a national track and field meet in Helsingborg, a vast improvement from his previous mark of 64.72 set in Jönköping one year earlier.

With his next attempt prompting a foul, Härstedt bowed out of the competition in tenth place.
