London Marathon: How Many Runners Achieve the Dream of a Negative Split?

Source: Financial Times
Author: John Burn-Murdoch

Best Practices:

  • Great use of color
  • Consistent design for each year and gender
  • Great axis labelling and descriptions
  • First chart has more descriptions than the others to make it easier to understand the entire viz
  • Well organised from newest to oldest
  • Layout makes the viz easy to consume
  • Comparisons are easy
  • Viz does a great job of answering the question in the title
  • Great use of reference lines
  • Fading out the runners that aren’t part of the story

Recommended Enhancements:

  • Subtitle is really long
  • Make the scales the same size, i.e., have the same number of hours on each axis, so that the 45 degree line is the same time for the first and second halves of the race
