Previous to Jornet, the TRT record was held by ultrarunning legend Tim Twietmeyer, 45h58m, set August 27-29, 2005. Among his many accomplishments, Twietmeyer has finished the Western States 100 mile an astonishing 25 times all under 24 hours, and won the race 5 times. An interview with Twietmeyer on his TRT record is here. Twietmeyer's trip was fully supported, including pacers much of the way. He ran the route clockwise, starting at the Truckee River in Tahoe City.
