We compiled a huge interactive chart that tallies, by hour and minute, more than 100,000 runners' finishing times in the 2014, 2015 and 2016 London Marathons.

Although everyone ran the same 26.2 miles, there was a lot of variance in the amount of time people spent the course, but there are also some common themes.

Running goals revealed?

The main thing that the chart shows is that while there's an overall bell shape to the curve, there are also definite spikes just before 30-minute peaks during the middle of the race.

Just before the 3:00, 3:30, 4:00, 4:30 times, there are definite peaks. Is that because several runners beat their target times? Is it some random coincidence? Are they following pace runners?

London Marathon runners' finish times, 2014-16


Our data is from the Virgin London Marathon website.

For simplicity, we rounded all finish times down to the nearest whole minute. So if someone finished at 4:22:38, their time was tallied as 4:22. Also, we only charted finishing times of eight hours or faster.
