How combined handicap works

Weight adjustment uses the Concept2 formula: time × (weight/270)^0.222. Age adjustment uses USRowing handicap percentages that increase with age (e.g. 50-54: 10.5%, 60-64: 18%). The combined score applies both corrections.

See our weight-only calculator for more detail on the C2 formula.
