Frequently asked questions
Symbols and assumptions
- Inputs
- The values entered in the fields above
- • For a measured swim: pace per 100 distance units=time×100/distance. At unchanged average speed, target time=time×target distance/measured distance. Match metres with metres or yards with yards.

- • Derived distance–time arithmetic, not a fatigue-adjusted swimming predictor. Concept2 supports the unit/time relation, not open-water performance; conditions, starts/turns and fatigue can change actual swim pace. Positive distance/time required.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
