Tour de Coffee Culture

10 June 2026

A mate at work mentioned a fun ride around Ōtautahi-Christchurch, where you visit all the Coffee Culture locations in Canterbury. Its called the Tour de Coffee Culture. As someone who studied maths, I know there is as much satisfaction to be gained in showing there is (propably) a solution as there is in actually doing the work. For this reason I went and brute forced the problem to find the fastest way to visit all the cafes. Better still, this did not require me to leave the house and actually cycle my bike.
