Hold the Dash button (L1 Default) and after a second once the Dash is finished, Arjun will enter a sprint! You can jump further, but can't Dash until you return to normal speed...

You can only activate this when Not in combat btw.

I've looked and there's no Tutorial entry or mention in the controls! (still on first biome though) But it does make crossing rooms and backtracking much quicker!
