Enter distance and finish time to calculate average pace, plus equivalent pace in the alternative unit system.
Inputs
The strongest pages in the library pair the live calculator with a topic guide and, where it helps, a printable reference you can reuse offline.
A stronger quick-reference sheet for one-rep max, pace, and heart-rate style training metrics.
A more substantial performance guide for pace and heart-rate planning, designed to keep effort zones and pacing decisions practical.
Use this calculator as a general pace planning tool when the underlying formula is useful but should not be overinterpreted.
The primary result is shown first, with supporting figures or notes underneath to make the assumption behind the output clear.
These tools are not medical advice and should be treated as general estimates. Individual circumstances can make the real answer different.
Use the Speed Calculator to solve speed from a standard physics relationship with explicit units.
Use the Calorie Burn Calculator as a general planning estimate with clear assumptions and careful interpretation.
Estimate a target training heart-rate range from age and chosen intensity percentages using a standard rule-of-thumb formula.
Estimate a daily hydration target from body weight, activity, and climate using a cautious planning-oriented approach.
