A 10K covers three or four kilometres of ground. At 150 mm that is a scale where real houses appear - not massed blocks, actual footprints with actual roofs. A 10K disc has more on it than a marathon disc does.
The 10k routes are being built and photographed. Yours can still be made today from your own file — which is the same model, made for one person.
Upload the GPX from your watch, from Strava or from the organiser, and the engine builds a 10K model from your actual track. You see it before you pay.
