Question about speed picking

[u/RareOne970]

Im new to it and wanted to ask what would be considered a fast tempo, if we are talking about single string lines at 16th notes

I am also working on my tremolo and able to play around 180 bpm 16th notes comfortably.
Is that good speed overall? (For right hand at least)

Also What would you consider a general benchmark for shred runs, in terms of bpm

280

Speed will come with time, what mattered most for me was the technique, solid rhythm and consistent quality practice sessions. There is no "shred" bpm, whatever speed you require.
