Hunter S. Thompson Fear & Loathing

Hunter S. Thompson Fear & Loathing is an urban long-distance event in San Francisco that offers a single-loop course starting and finishing at Twin Peaks. The route passes many tourist areas of the city and encourages self-navigation; getting lost is described as part of the experience. Two route distances are offered:

  • 50 Miler
  • 50K

This event is organized as a "fat ass" format with the stated motto "No Fees, No Awards, No Aid, No Wimps." Volunteers typically provide aid stations, but they are not guaranteed. Aid stations are usually located at approximately mile 0 (Twin Peaks), mile 6 (Cesar Chavez / 3rd St), mile 14 (Geary & Webster), mile 17 (Coit Tower / Grant Ave & Lombard St), mile 20 (Marina Green), mile 25 (30th Ave & El Camino del Mar), mile 32 (Lake Merced), mile 38 (Sunset Blvd), mile 44 (Stanyan St), and mile 50 (Twin Peaks).

There is a cutoff at mile 25 of four hours and forty-five minutes; participants who do not meet that cutoff are directed onto the 50K route. Beginning in 2024, 50 mile finishers are required to run an additional 0.67 mile loop around Twin Peaks after returning, to record the full 50 miles. The event supports the Shoes For Runners charity and serves as a qualifier for the Ohlone Wilderness 50K Trail Run. Visit the organization's website for the most recent information.
