Running Tools

Calculators I built based on apps I've used in the past. Fun to obsess over!

Pace Calculator

Fill in any two of distance, time and pace. The third is worked out for you.
Race Time Predictor

Turn a recent race result into predicted times for 5K, 10K, half and marathon.
Splits & Pace Band

Checkpoint splits for a target time, printable as a race-morning wrist band.
Race Night

Back a runner, hit start, and watch the field battle it out. Purely for the craic.
