On November 15, 2015, more than 30 people including artists, adventure-racers, casual joggers, track-champions, walkers, and other member of the general public ran from Old Mill subway station in Toronto to Sherborne Subway station, following four major urban watersheds. The route followed the Humber River from Bloor Street to the Black Creek, crossed the North York hydro corridor north of Finch Avenue, joined the West Don River and followed the main artery of the Don River to the finish at Bloor Street, passing under the 401 twice. Covering 55 kilometres in total, the route took more than nine hours, and almost entirely followed riverbanks and ravine trails. Two people finished the entire distance.
