I had a bike commute where I happened to join the 2026 May 3rd 5 borough bike tour1. I was curious how much overlap I had.

The below is an overlay output from a vibe coded ChatGPT session, extracting the overlay data using gpx from my strava data and gpx from the bike tour that looks like is here2. So in my mind it felt like 5 miles. And looks like it was about 5.92 miles.

Will post the code here too later.
