Did Cooler Weather Lead to Faster Times at London?

As the leg stiffness starts to fade into a distant memory for the 42,000+ runners that took part in the Virgin Money London Marathon on Sunday, Mike Clyne has taken a quick look at the stats and updated our pre-race article.

Cool conditions seem to have given the record number of London Marathon competitors an opportunity to run faster (on average) than their predecessors in the 2018 event. For those that tackled the 26.2 miles a year ago in the hottest conditions that have ever faced the event it will have been an unforgettable experience and the finish times (see table below) across the board were slower than previous years.

Last Sunday’s ‘official’ temperatures have not been confirmed but by my basic research seem to have been similar to those experienced in 2017 (ranging from about 10 – 14 degrees C) and you will see that the finish times for the various data points are also similar to 2017.

You will also note that the percentage of runners who started and then finished was just under 99.2% – astoundingly great odds for those on the start line but as you will see from the table it is not the highest percentage (2015 race – 99.4%).

I’m continuously curious about what happened to the 315 people who registered at the London Running Show but didn’t start the race (43,221 registered but only 42,906 started) – what happened in the days and hours between to prevent them running?

Take a look at the stats and see what trends interest you. And don’t forget the ballot closes at 1700hrs on Friday 3rd May.
