About This GPX Running Splits Calculator

This GPX running splits calculator gives runners fast, precise feedback without heavy dashboards. Calculations happen locally for accuracy within seconds, letting you focus on insights instead of waiting for syncs. Benchmarking Reddit discussions and coaching forums inspired a lighter alternative with export-ready tables, pace cues, and shareable summaries that serve solo athletes and whole squads alike.

Kadence-inspired styling keeps the layout breathable on track-side phones and spacious desktops. Semantic HTML, visible focus states, and keyboard friendly controls remove friction for every teammate. The parsing pipeline minimises layout shifts, helping Core Web Vitals stay under a 0.1 CLS for reliably smooth sessions.

Unlike paywalled competitors, no account is required and your GPX file never leaves the browser. Generate a permalink that stores the analysed splits or download the CSV for spreadsheets and coaching platforms without retyping data.

How to Use

Upload any GPX file from your watch or phone, pick kilometre or mile splits, set your target interval, and optionally smooth brief pauses from auto-stop. Press “Analyze GPX” to see pace, speed, elevation, and timestamps in a tidy table. Export the CSV, copy headline metrics, or create a permalink to share the summary instantly.

Tips

Set shorter splits for interval diagnostics and longer ones for races to reveal macro pacing trends. Adjust the smoothing threshold if GPS noise adds phantom pauses. Pair the exported CSV with conditional formatting or pivot tables to highlight negative splits, hill surges, and fatigue markers in seconds. Revisit the permalink after races to compare pacing patterns season over season.
