The Tahoe 200 Endurance Run 2017 was the first ever 200 mile single loop mountain event in the United States and the route circumnavigates Lake Tahoe from the Tahoe Rim Trail. The race is a non-stop traverse of the lake, with numerous aid and sleep stations. It forms part of a triple crown of 200 mile trail races, with BigFoot 200 and Moab 200. Cutoff for Tahoe is 100 hours.
The event is about 19 hours in as I write and Jovica Spajic leads the men and Sofi Cantilo leads the women.
