Countdown (Ver. 30-20-10) is a timed training track created for runners using the 30-20-10 interval method.

The track provides structured audio cues through the repeated 30-second, 20-second and 10-second phases, making it easier to follow the workout without constantly checking a watch or timer. Built around a steady electronic pulse, it combines practical pacing guidance with enough energy to support repeated high-intensity running intervals.
