During COVID I made it a goal to walk every street in my town using the web-based CityStrides (https://citystrides.com/) tracker. It keeps tracks of streets you have walked and lets you know what percentage of a town you have walked. It didn't optimize my routes for coverage, but it was a fun mental puzzle to plan out my walks to hit as many streets as possible without duplication. An automated tool might be fun, but doing it by hand was part of the journey as it were.

As you browse the CityStrides site you can find people's LifeMaps which show all their walking. Some people have done amazing amounts of walking. See this user for example and their coverage of Paris, France...
