- • Derived distance/time arithmetic; Concept2 supplies an official example of pace, time and distance relationships, not a running performance prediction. Use consistent distance units, positive race distance and valid checkpoint order. Label cumulative versus segment times and do not round intermediate values.
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.
