What's Up in Ultra This Weekend — December 27, 2025

Featured: New Year’s One Day (San Jose, CA)

The New Year’s One Day kicks off at 9 a.m. PST on December 31 at Hellyer Park in San Jose, California. Established in 2010, the event gives runners a unique way to close out the year with 6 or 12-hour races, or to ring in the New Year by tackling the 24-hour or 100-mile events, which run through the night and finish on New Year’s Day. All events take place on a 1.03-mile USATF-certified course that runs around Cottonwood Lake on an asphalt path. Race perks include great swag, a fully stocked aid station every mile that serves hot soup and pizza for the evening runners, and special buckles for runners who complete 100k or 100 miles in the 24-hour race, or who finish the 100-miler.

Featured: Last Supper 100k (Roxbury, NJ)

Described as “an unsanctioned, semi-stupid, fully glorious end-of-year ultra,” the Last Supper 100k was dreamed up as a way for local Roxbury, New Jersey, ultrarunners to close out the year with a bang. The race features a single 100k loop that starts at Horseshoe Lake and winds through a mix of 70% roads and 30% trails, and totals just over 4,000 feet of elevation gain and loss. The race kicks off at 7 a.m. on Saturday, December 27, and runners must complete the loop before the clock strikes midnight to earn an official finisher medal (and a banana). Read more.
