Before You Go, and When You Come Back

Before You Go

Prepare your routes before heading out. Whether you're planning a training ride, an adventure, or just want to explore a new area, GPXFIT helps you get your route files ready.

  • Edit waypoints to add or rename points of interest, cafes, water stops, or scenic viewpoints along your route
  • Create a ghost racer to set a virtual competitor on your GPS device for interval training or pacing
  • Trim or crop routes to remove sections you don't need or adjust start/end points
  • Split long routes into manageable day stages for multi-day adventures
  • Combine shorter routes to create one continuous file from multiple segments
  • Verify elevation data to double-check climbing stats and prepare for what's ahead
  • View your route in 3D to visualize the terrain and get a feel for the ride before you start

When You Come Back

After recording your activity on a bike computer or fitness device, GPXFIT helps you clean up, analyze, and prepare your files before sharing.

  • Analyze your performance with power curves, HR analysis, training zones, and segment breakdowns
  • View detailed gradient reports to see how much time you spent on different inclines
  • Trim the start and end to remove the ride from your house to the actual route start
  • Remove still time to clean up long stops at traffic lights or cafe breaks
  • Protect your privacy by scrubbing location data near your home, cropping start and end points, or moving your entire route to a different place in the world
  • Fix elevation anomalies if your GPS recorded spikes or drops that skew your stats
  • Export in multiple formats including GPX, FIT, CSV, and GeoJSON for compatibility with any platform

We're not trying to be the most advanced analysis platform out there — there are excellent tools for that. Our goal is to bring together a collection of useful and sometimes hard-to-find tools in one place, making it easy to prepare, edit, and clean up your GPS files without needing multiple apps.

Multi-Route Event Planner

Plan multi-loop and multi-day events by assembling routes into a timed sequence. Set per-loop speeds, schedule overnight stops with start-time overrides, view sunrise/sunset conditions, and export your plan as GPX, Markdown, or a printable report.

GPX, FIT, or GeoJSON?

Three formats power the GPS world, but they are built for very different purposes. GPX keeps things simple and portable, FIT packs in detailed fitness data from your devices, and GeoJSON speaks the language of web maps and developers. Knowing when to use each one can save you time and headaches.
