The Lower Loop of Central Park is a very common spot for New York runners to do workouts on because of its relatively low elevation gain compared to the rest of the park. The transverse at 72nd street brings runners by the iconic Bethesda Fountain. The loop is run counter clockwise, notably passing Tavern on the Green, the Great Lawn, and Columbus Circle. The FKT is determined by most loops run during the open hours of Central Park, from 6AM - 1AM or 19 hours. 

This route can be run in both directions with easy access to both entry points from Hamburg main station. The route follows a beautiful topological feature called "The High Moraine", which was formed during the last ice-age. About 50% of the route also follows the Elbe riverbank and most of the route is in forest on easy trails. Parts of the route traverse areas of special natural interest (and protection).
