Click a distance column — its heading above the chart (30mi), or anywhere in the
column itself — to see the places at that distance. Click another column and it moves there; click the same
one again to close it.
Drag a finger across the chart on a phone or tablet and the places follow it, column by column.
Click a runner in the legend on a phone to pick their line out of the field and hold it there. The
columns then show that runner's own place and time at each distance. Click them again to bring the field back.
The legend scrolls, and the pickers above change the race, how often the field is sampled, and which runners are shown.
