Slide Ratio

What is Slide Ratio?

Slide ratio measures the time spent on the drive relative to the recovery. A ratio of 1:2 means the recovery takes twice as long as the drive — this is the target for most rowing. At 20 strokes per minute, each stroke cycle is 3 seconds: 1 second drive, 2 seconds recovery. Good slide ratio creates rhythm, reduces energy waste, and allows the flywheel to decelerate naturally between strokes. Poor slide ratio (rushing the recovery, approaching 1:1) increases fatigue, disrupts timing, and creates a harsh, jerky catch. Slide ratio naturally shifts during racing — at 32+ spm the ratio approaches 1:1.5 — but for training and steady state, maintaining 1:2 is critical for efficiency and injury prevention.
