Method and calculation
The Riegel estimate scales time by the distance ratio raised to 1.06.
Inputs and settings
Race Time Predictor accepts Completed distance (km) (minimum 0.000001); Completed time (minutes) (minimum 0.000001); Target distance (km) (minimum 0.000001).
Worked example
Race Time Predictor example — Completed distance (km): 5; Completed time (minutes): 25; Target distance (km): 10. Computed output: { "estimatedMinutes": 52.12328804205607 }
Output and limitations
Race Time Predictor: An endurance estimate using exponent 1.06, not a guaranteed race performance.
