The GPX data of this course
The smoothed profile is stored every 50 metres: 845 points with latitude, longitude, elevation and gradient. The elevations here do not come from the course file but from a terrain model: the ones in the original were unusable.
We do not hand this course out as a file: the line comes from a third-party source and is not ours to pass on. Once a course is built from runners’ own recordings, the file appears here.
