Running & Family-Fitness Calculators
Free, practical tools for running parents — check your pace and calories, predict a race time, build back to 5K, work out how much a stroller slows you down, and plan run/walk intervals around real life.
Running Pace Calculator
Turn a distance and a finish time into your pace per kilometre and per mile, plus your speed in km/h and mph.
Running Calorie Calculator
Estimate the calories you burn on a run from your weight, distance, and pace, using the MET method with a terrain adjustment.
Race Time Predictor
Predict your finish time at a new distance from a recent race result, using Riegel's formula, with the pace you'd need to hold.
Couch to 5K Planner
A nine-week run/walk schedule that builds to a continuous 5K, with a starting point matched to your current level.
Stroller Pace Adjuster
See roughly how much a running stroller slows you down, from your flat solo pace and the combined stroller-plus-child weight.
Run/Walk Interval Calculator
Plan a Galloway-style session — enter a duration and a run:walk ratio to see your intervals and total run and walk time.
