Some (many!) years ago I posted a few images showing my riding history in California (in 2008) and Colorado (in 2012). While they are interesting, these are static images and cannot be explored.
Thirteen years have passed and technology has improved. Today I added a new page showing my entire cycling history since I started using GPS over twenty years ago. Instead of separate static images, it uses dynamic web technology™️ on a single map. As before, color shows how frequently I ride past a point on the map. However, I changed the logic: my previous maps used counts of observations near points, my new map uses counts of distinct rides that pass each point on the map. Instead of where I've done the most laps or my GPS has recorded the most times (for whatever reason), this is more indicative of where I ride the most.
For the most immersive experience, here is the full screen version.
