How to use this calculator
What to enter
Enter or select the following as requested: Total mass; Speed; Road grade; Headwind; Rolling resistance (Crr); Aerodynamic area (CdA). Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The result estimates a sports performance, pace, workload, score, or training metric from the values entered. Check units, timing method, event rules, and whether the calculation assumes constant pace or ideal conditions.
When to use it
Use this for training plans or informal performance comparisons. Treat the result as an estimate and adjust for individual condition, equipment, environment, and relevant coaching or medical advice.
