You might be interested in this analysis I did, where I downloaded the training data for 1,000 strava athletes in the lead up to VLM 2016. I then compared their training patterns to a number of Runner's World marathon plans:http://blog.scottlogic.com/2017/02/28/london-marathon-training-visualisation.html
Interestingly people are putting in far fewer miles than the plans suggest. Those achieving a sub 4:00 marathon time are running 34% fewer miles than the Runner's World plan!
