See a route in 3D, fix or convert a file, read its climbs, and take it outside: onto your watch, into a good weather window, and into days that fit. Every tool is free and needs no account, and a file you open in one can be passed to the next without choosing it again.
Look at a route before you commit to it: its shape, its climbs, and how it compares with another.
Fly any race or trail route, or your own GPX, over 3D terrain with open aerial imagery where it exists, in your browser, with separate days as separate sections.
An elevation profile with ascent and descent from the heights in your file, counted like the Course Analyzer and Route Packet count them. A terrain estimate when the file has none.
Break a course into its climbs and descents: length, gain, average grade, steepness and the crux climb.
Put two routes side by side: distance, climb, estimated time and how much of the path they share. Then continue with the one you choose.
Get a GPX into the shape a watch, app or planner needs, without losing what is in it.
Make a GPX smaller and see what that does to its distance and climb. Segments, waypoints and times are kept.
Turn a FIT or TCX file from Garmin, COROS or Suunto into a GPX, and a TCX course. Says what a GPX cannot carry.
Combine several files into one: each day or recording as its own segment, or joined into one line with the gaps shown.
Remove timestamps, device metadata and extensions for a plain GPX that imports anywhere and does not say when you ran.
Take a route outside: onto your watch, into a weather window, and into days that fit.
A clean GPX and a TCX course, with step-by-step import instructions for Garmin, COROS, Suunto, Wahoo and Komoot.
A 7-day forecast at the route’s high point, day by day, with thunderstorms and missing data said plainly.
Snow conditions along a route now and over the next 24 to 48 hours.
Split a trail into balanced days with distance, ascent and time, and a GPX for each day. For hut-to-hut trips and fastpacking.
How the TrailSplits Planner works: draw a route, import a GPX, make a loop, fly it in 3D and export it, without an account.
Numbers for the day itself and the weeks before it.
Target pace and split tables for a standard distance or your own GPX course, slower where it climbs; equivalent race times and training paces.
Grade Adjusted Pace from a recorded run (a GPX with times): your flat-equivalent speed on a hilly run.
Water and calories for the distance and climb ahead, so you do not run out halfway.
Turn a mountain course into an incline plan for a gym treadmill.
A repeating 4-week training plan for long-term trail running health, with no race to aim at. Adds to your calendar.
Nine weeks of run-walk, three days a week, to 30 minutes of running. For people who do not run yet. Adds to your calendar.
Experiments that work, but are not finished products.
When a tool has your route, its links to the next tool take the route with them: from the converter to the course analyzer and on to your watch, from the simplifier into a 3D flyover, from a comparison into the forecast for the route you chose. The file is kept in this browser tab for two hours, so Back and a refresh keep working; it is not uploaded, and another tab or device does not see it.
Your GPX file is read in your browser and is not uploaded. The flyover and maps load imagery and terrain for the area you look at; the weather, snow and terrain-estimate tools send the route's coordinates (or a representative point) to those services to answer.
