  Hi Laurent,

  Thanks for providing such a detailed bug report.

  To confirm your finding, I tested importing the GPX to Visorando, and the result is yet another: 151,79km vs 150.699 on Plotaroute and 152.8km on RwGPS.

  I don't know how this is handled on the tech side, so I'll share this with the devs.

  I'll update this topic as soon as I receive any news on this.

  All the best,
  Julien

  Hi Julien

  Thank you for your answer ; further to your request, I sent a .gpx file to your helpdesk - not the file I mentioned in my question but a lighter one, with which I get the same discrepancy : 152,8 km on RwGPS and 150,699 km on Plotaroute.

  I downloaded the same .gpx file to other websites that I know (but almost never use) ; most of them show a length of 152,6 / 152,75 km so I would think that the bug lies with Plotaroute : for the same .gpx file, I get : VisuGPX : 152,65 km ; RouteYou : 152,6 km ; cronoescalada : 152,6 km ; Komoot : 153 km ;  GPSVisualizer : 152,746 km ; Strava : 152,73 km

  I also downloaded a gpx file that I made with Plotaroute in 2025 : it showed 202,6 km then, it shows 202,6 km on Ridewith GPS to-day but only 201,847 km on Plotaroute.

  I am surprised no one seems to have come across the same problem. No idea when this bug appeared as I had not used Plotaroute or any other website since last October (and it was OK then)

  Plotaroute is a tremendous resource with many features which do not existe elsewhere, I hope this bug will be resolved soon. 

  Thank you for your help.

  Hi Laurent,

  Could you send me a link to the route or the GPX via the help desk?

  This way I can take a look and report this to the devs if this is a bug.

  Thanks,
  Julien

  Hi

  I had not used Plotaroute for some time but to-day I wanted to plot the Ronde van Vlaanderen route. Plotaroute is a great tool for this thanks to its very useful features. 

  Plotaroute showed a distance of 275,8 km ; I downloaded the .gpx file on another tool (RidewithGPS) which showed a length of 277,5 km (race website announces 277,4 km). 

  When I was a frequent user of both sites, both showed exactly the same length for any .gpx file that I downloaded.

  Wondering what happened.
