Normalised Comparison
With this variation of the chart we normalise the chart so that the
start line is at the same level, this way you can compare the two
parkruns in an alternative way.
Bottomed out Comparison
The below charts move the lowest point to the bottom so you can compare
in another way.
Sorted Comparison
Finally the below chart sorts all of the elevation data to give you a
rough indication of the change in elevation you'll be. Typically if one
line is steeper than the other, the steeper parkrun might be more of a
challenging run.
