About the extended functions

The extended section turns the calculator into a full running log. Same rules as the basic side: ad-free, no account, privacy-first, no cloud. Data stays on your device, optionally exported as a CSV file you own.

Log your runs. Distance, time, date, notes — per run. Personal records for 5K, 10K, half marathon, marathon and any custom distance you set are detected and marked automatically.

Progress chart. Pace and distance over weeks or months, with switchable views. Helps you see whether your training is actually producing fitness gains, without you having to interpret raw numbers.

Group runs. Running club, family run, team event — the group run comparison page ranks multiple runners on the same distance. Time, pace, steps and notes per person, with a chart and a ranking. CSV import and export, so the group result lives wherever you need it.

CSV import & export. Bring in existing data from Strava, Garmin Connect or your own spreadsheet via CSV. Templates are linked from the gateway. Your data stays portable — even if you stop using this calculator one day.

A running log that belongs to you

No account, two ways to store. Choose CSV file mode to keep your running log in a CSV you download and re-upload (it opens in Excel, Numbers or Google Sheets), or Browser mode to keep it in this browser's local storage with one click on "Save to browser". Nothing is sent to a server either way.

What gets tracked. Date, distance, time, optional step count and notes per run or walk. Pace is derived automatically; with steps the run tracker also shows your stride length. Personal records are detected for 5K, 10K, half marathon, marathon and every other distance you log, ranked by pace, distance or steps.

Progress chart. Pace, distance, time or steps over 1 month to all time, with personal bests highlighted. Filter by running, walking or both.

Group runs. Running club, family run or team event? The group run comparison ranks everyone on the same course by time, pace or steps. If you ran in the group yourself, import your own result from the group CSV straight into your log.

Importing existing data. Export a CSV from Strava, Garmin Connect or your spreadsheet, match the columns to the template (date, distance_km, duration, steps, notes, mode) and upload it. Demo data is shown until you load your own.
