Running calculators

A few tools I’ve built for planning my own running. Work out a session, compare race times or put a training schedule on the calendar.

Interval session

Add up reps, recoveries, warm-up and cooldown. All distances are in kilometres.

Equivalent race times

Enter a recent race result to compare estimated times over other distances.

Training-plan calendar

Choose an existing schedule and work backwards from your race date.

Plans from: time-to-run plan collection

These are reference schedules, not personalised coaching. Choose a plan that fits your current training and adapt it to your circumstances.

Pace chart

A quick reference for kilometre and mile paces, distance splits and finishing times.
