As professionals in the GIS (Geographic Information System) field, we engage with geographical data, spatial analysis, and visualization technologies daily. Recently, I discovered an impressive website called "No Days Off" on HackerNews. Developed by friggeri using 10 years of daily running GPX files, this site functions as a sophisticated "personal running GIS system," showcasing remarkable professionalism and engagement. I'm fascinated by such innovative projects and would like to share its details.
