In any open or long area, such as the beginning of Chapter 2 - Jacknife, reach full speed and maintain it for 30 seconds. Don't jump or stop moving, as this will disrupt and reset the 30 seconds. Once you have maintained sprint speed for 30 seconds, stop running and the trophy will unlock.

Below is a video demonstrating this in Chapter 2 - Jacknife. Credit for the video goes to FocalPointGaming.
