A GPX file is a list of coordinates. A GPX poster is that list drawn as one line on paper, at the size of a wall, with the numbers the file carries set underneath. Drop the file in, and it is drawn in your browser before you have decided anything — no account, no upload, no waiting for a proof.
Any GPX, from anywhere
Garmin Connect, Strava, Komoot, Ride with GPS, Apple Watch, Coros, Suunto, Polar, Wahoo, AllTrails, a hiking app, a sailing app, a file somebody emailed you in 2014. If it is a GPX it is drawn; FIT and TCX are read too, zipped or not, and the format is sniffed from the file itself rather than trusted from its name. GPX, FIT or TCX explains what each carries, and the Strava guides cover getting a file out of Strava in particular.
Several activities in one file are split apart, and you pick the subject. Several files at once are drawn together — a multi-day walk, a week of riding, a whole year for a heatmap.
What is drawn, and from what
The shape comes from the coordinates. The numbers come from the file's own summary where it has one — distance, moving time, elevation gain, pace or speed, the date — and are computed from the points where it does not. A route file without timestamps gets a shape and no time; a treadmill file without coordinates gets nothing to draw, and the editor says so at the door. Nothing is invented. What the numbers mean and what your file carries go through it field by field.
The line is a vector drawn from the points, so it is sharp at 70×100 cm. Long recordings with tens of thousands of points are simplified to what the eye can see at print size — why a printed route has fewer points.
Line, or map
The default is the clean line: the route on plain paper, the numbers under it. Choose a map style — seven of them, from a pale paper map to terrain — and it becomes a map print with the roads around the route and the map's attribution on the sheet. Switch between the two live and decide with your eyes.
Privacy, before anything is drawn
The first and last 500 metres are clipped in your browser before the route is rendered, so the line starts on a road rather than at your front door, and you can push the trim out to two kilometres. The untrimmed file never leaves your machine; only the trimmed, finished route travels with the order. Sharing a route safely is about the same file.
Sizes, paper, frame
Route print: 30×40, 50×70 or 70×100 cm on Museum 250 gsm or Classic 170 gsm, both uncoated matte, from 319 kr. Framed behind acrylic glazing in a solid wood frame — white, black, wood or dark wood — ready to hang, from 799 kr. Two to four working days to make, then shipping inside the EU.
Drop the file in and see it. If it came from Strava, Strava prints is the page written for you.
