Where do I get my marathon's GPX file?

Export it from Strava, Garmin Connect, or any GPS watch app after your run. For races you didn't run with a watch, most major marathons publish an official course GPX, and aggregator sites like goandrace offer downloadable tracks.

Does Cartosketch keep my exact route?

The route line is overlaid from your uploaded coordinates on an AI-generated basemap. GPS data can contain errors, and the artistic background may change geographic details; review the result before printing.

What size should I generate for a poster?

Choose a ratio such as 2:3 or 3:4 and check the downloaded image’s actual pixels. Print size in inches = pixels ÷ target PPI; 3000 pixels at 300 PPI gives 10 inches (25.4 cm). Up to 4K does not guarantee A2/A3 quality; confirm sizing with your printer.

Can I sell prints of race routes?

Yes. Any paid plan (Credit Pack, Plus, Pro) includes full commercial rights for finisher prints, run-club merch, and print-on-demand products. Note that race names and logos are trademarks of their organizers — sell the route art, not the branding.
