New Year's One Day

Participants can enter individually or as part of a team, choosing from 6-hour, 12-hour, 24-hour, or 100-mile options.

The venue is the Buena Vista Pavilion at Hellyer County Park,

with runners repeating an approximately 1.03-mile (1.66 km) paved loop around Cottonwood Lake with very little elevation change.

The event was originally held at Crissy Field near the Golden Gate Bridge,

but is reported to have moved to its current location after the Golden Gate National Recreation Area (GGNRA) stopped allowing overnight events.

Registration is available through RunSignup.

Based on the previous year's announcement, the early-bird rate applied until midnight on November 30, after which prices increased.

Finishers in the 24-hour and 12-hour solo categories receive a fleece hoodie at check-in,

while finishers in every category except the 100-mile event receive a finisher finisher medal and a coaster engraved with their name and finishing distance.

The awards ceremony begins at 9:15 a.m. on January 1, New Year's Day, starting with the 24-hour category.
