The NYC Toilet Challenge: A 579-Mile Marathon Nobody Asked For
Did you not make it into the NYC marathon this year? I have an alternative for you…
If you have the right mixture of ambition and questionable GI state, then here is a route that connects all of NYC’s public restrooms for you:

In total it is a mere ~579 miles as the crow flies. At 100 calories per mile, that is 57,900 calories required, or about 165 Beef Chalupa Supremes.
This was generated using NYC’s open dataset on public restrooms. Since solving the shortest path is tantamount to the traveling salesman problem, this is an approximation using nearest neighbors with some pre-computed clusters (and special handling for Staten Island, because, well, Staten Island is special…). The route looks reminicent of the listeria adhesion protein shape that is probably very active in anyone’s belly that attempts this.
Tighten your laces, eat that questionable leftover food from last night on your counter, and I will see you out there.
