Hunter S. Thompson Fear & Loathing

Embrace the Spirit of San Francisco with Hunter S. Thompson's "Fear and Loathing" Ultra Race, jointly presented by the storied Haight Ashbury Ultra Society since 1985, Zombie Runners from 2006 to 2011, and Fat Ass Runners starting in 2012. This unique event invites you to experience San Francisco's iconic landmarks on foot through a challenging yet scenic course that spans either 50 kilometers or the full marathon distance of 50 miles.
The adventure begins at sunrise atop Twin Peaks, the city’s highest point, offering breathtaking views as you launch into your journey. The single-loop route takes runners through some of San Francisco's most recognizable locations, including Fisherman's Wharf, Chinatown, and Golden Gate Park, while testing your navigation skills with intentional detours and opportunities to get lost.
Aid stations are minimal but strategically placed along the course: at Mile 6 near Cesar Chavez Street, Mile 14 in Japantown, Mile 20 by Coit Tower, Mile 32 around Lake Merced, and more. These stops offer a chance for runners to refuel with pastries from local bakeries like those found at the Ferry Building Marketplace or cappuccinos from North Beach cafes.
For those aiming to complete the full 50 miles, reaching Mile 25 within an ambitious 4 hours and 45 minutes is crucial. If you make this cutoff time, you'll continue on for another challenging loop around Twin Peaks to hit the true mark of 50 miles. Otherwise, runners are encouraged to switch to the 50K route before heading back home.
This event celebrates its commitment to community service through support for Noé Castañón's Shoes For Runners charity since 2012, providing running gear and shoes to underprivileged communities in Mexico and beyond.
Join us as we honor Hunter S. Thompson’s legacy of fearless exploration and embrace the spirit of San Francisco’s rich history with this unforgettable urban ultra adventure.
