I’m really into this gps game: https://wandrer.earth (I’m not the creator, just a fan)
It encourages you to walk/run/bike all the roads in a town/city/county and it tracks the percentage.
It’s a fun and creative way to go see parts of your area you wouldn’t otherwise. I’ve used it to walk 97% of the miles in Berkeley and seen so many funky little areas. I also really enjoy how much it has increased my walking over the last few years.
