I suspect Ari and Bridget are the only people who know what I'm talking about. :)
The streets in CityStrides
, a site for tracking your progress in trying to run every street of a city, are defined by nodes. Nodes are points along the street and at intersections and a street counts as complete once you've passed within 20m (or something like that) of all of the nodes along that street.
There's a map viewing mode on the site called "node hunter" that helps you find the nodes you still need to hit. I think you can see an example of nodes in an activity
if you go to the completed or progressed streets and click "show" on some of them.
I have almost 30% of Cambridge complete and this is a great time to be node hunting because running on all the random side streets is a great way to avoid crowds compared to the popular river paths. I'll be back to it tomorrow!
