*Please note that I do not expect this set of marathons to be complete. If your favorite marathon is missing,
let me know and I can about it add it to the plots!
If you'd like to see
a temperature history of race day for a particular marathon (click on Boston or New York in the temperature tab for examples), feel free to send me a list of the race dates for the past few years, and I can add in the corresponding temperature data.
Here is a blog post describing the making of these plots.
