This community is a clearinghouse for datasets related to analyses that I publish on Running with Rock and in Runner's Life on Medium.
I initially started collecting and analyzing data related to marathons because I was frustrated with the quality of analysis and discussion out there. There were very few public datasets, and the organizations that published "research" based on their own private datasets often shared lazy and inaccurate findings.
I've been collecting results in order to analyze trends in finish times, better understand the impacts of weather, and investigate the changing demographics of marathon runners. I'm sharing these datasets publicly in case anyone else is interested in using them for some purpose.
