Stage lengths

Excluding (team) time trials.

I use "normal" notation: the red line is the median value, the brown bar runs from the 25% percentile to the 75% percentile. If a point is more than 150% of the brown bar length away from this brown bar, it is seen as an outlier and shown with a black dot. The red vertical line connects the non-outliers.
