Jonne Koski

One of CrossFit’s brightest rising stars, Rogue athlete Jonne Koski first made waves on the international scene in 2014, winning the Euro Regionals at just 19 years old. A year later, he claimed 1st place at the expanded Meridian Regional and impressed fans with a 9th-place finish at the CrossFit Games. After withdrawing due to injury in 2016, Jonne bounced back with a Top 10 finish at the 2017 Games, highlighted by standout 2nd-place performances in the “Run Swim Run” and “Triple G Chipper” events.

Jonne’s momentum has only continued to build. In 2023, he earned a strong podium finish at the Dubai CrossFit Championship and delivered consistent top placements throughout the season. He also competed at the Rogue Invitational, further showcasing his skills against some of the world’s best athletes.

Jonne’s athletic roots run deep—he spent six years competing as a youth swimmer in his native Finland before shifting focus to CrossFit at 16. Guided early on by fellow Finnish Rogue athlete and 2009 CrossFit Games champion Mikko Salo, Jonne continues to train out of CF Varasto in his hometown of Pori, Finland, where his determination and skill keep pushing the limits of what’s possible.
