The 24-year-old had previously stated a clear goal: to break the dream limit of 30 minutes over ten kilometers.
But it was not a full hit this time. Poromaa crossed the finish line at 31.27, just over one and a half minutes over the longed-for time.
The victory went to Sebastian Lörstad, born 2008, who impressed greatly with 28.53, just over two and a half minutes ahead of Poromaa.
Although the goal of 30 minutes cracked, the ski profile could still be pleased with a respectable 28th place in the strong starting field.
