Video: Measuring swim route distance in a river


Open water swimming distances are measured by the shortest swimmable path between the start and finish. The easiest way to do this is with the “Measure distance” tool in Google Maps. In this video we work through a somewhat complicated example in the Iron Gates region of the Danube River.

Romanian marathon swimmer Avram Iancu completed a 103.8 km swim in this area in August 2020.
