What % of Manhattan Did I Run Through?

In a previous post I created a cool-looking (in my opinion) heatmap of my Marathon training from years back. One of the downsides to that density-based method of making the heat map was that routes I only ran once didn’t show up very clearly.

Heatmapping My New York City Marathon Training

Motivation This post was inspired by my wife who used the GPS data from her Strava app to plot her running routes during 2020. Since I don’t run nearly as much as I used to, I need to go back to when I was training for the NYC marathon to find enough running to make such a map worthwhile.
