SpeedRun Achievement

[Flaywint]

In achievement lists say "Complete a full speed run, beating the challenge time."
It's a full game speedrun challenge or any speed test?
Because I do 25,95s of 26s and didn't unlock this.
In pt-br says "a speed test", I understand that any test is worth...

As I remember it's a full game speedrun. But I would recommend to complete level speedruns first so you can use those tricks in full game speedrun later.
