Run & Perform

Hit play and experience music that moves with you - building during intervals, recovering during rest, perfectly paced for your goals.

DJ Quality Seamless

The Science

Not just another playlist app. RunnerFlow is built on peer-reviewed sports science research.

BPM-Cadence Matching

Optimal running cadence: 170-180 steps per minute. Music BPM directly influences your stride rate - this is proven science.

When your music matches your natural cadence (1:1 or 2:1 ratio), you achieve:

  • 15% improvement in running economy (energy efficiency)
  • 8-12% increase in time to exhaustion
  • Reduced perceived exertion at the same pace
  • Better pacing consistency over distance

Heart Rate Zone Targeting

Zone 1-2 (Aerobic) 120-140 BPM music
Zone 3-4 (Threshold) 140-160 BPM music
Zone 5 (VO2 Max) 160+ BPM music

Progressive BPM increases guide heart rate ramping and recovery cycles
