Race time predictor
Use one known race result to estimate another distance. This is the only estimated model in this toolkit; pace conversions elsewhere are exact.
Formula: t2 = t1 x (d2 / d1)^1.06
Example: A 25:00 5K predicts about 52:07 for 10K.

| 50K | 4:47:02 | 5:44 /km |
FAQ
Is the race predictor exact?
No. It is an empirical estimate. The input distance and time are exact, but the performance model is approximate.
What exponent is used?
The default exponent is 1.06, the common Riegel scaling exponent.
