Hunter S. Thompson Fear & Loathing

Midtown Terrace, United States • 7 Dec 2025

The Hunter S. Thompson Fear & Loathing is a unique ultra running event held annually in San Francisco, CA, since 1985. It offers two distances: a 50K and a 50-mile single-loop course starting and finishing at Twin Peaks, the city's highest viewpoint.

The route covers iconic city landmarks and features a total elevation gain and loss of 3,600 feet, with mostly city streets and some trail options on the 50-mile course. This "fat ass" style race has no entry fees, awards, or mandatory aid, though several aid stations are typically available. It emphasizes navigation skills and urban adventure, challenging runners to embrace getting lost while enjoying the scenic cityscape.
