All of this data I collected while on a trip, usually by moped/🛵.
It started as tracking some running I was doing for a race (click to zoom to that view), then biking, then walks, then I got a scooter and started scooting all over the place.
It's collected via the Strava app, and then I've fetched bits of that data from their API, and am rendering it all at once on this map.
I no longer live in Golden, but originally enjoyed the pac-man-like sense of 'filling in' an increasingly large amount of the street network.
