New Year's One Day takes place at Hellyer County Park, Buena Vista Pavilion, 985 Hellyer Ave, San Jose, CA 95111, on 12/31/2026. The event uses a certified 1.0 mile loop around Cottonwood Lake in Hellyer Park, USATF certification CA23033TEB.

The event program includes fixed-time solo and team formats. Fixed-time events allow participants to run or walk as far or as little as they want within the time limit.

The team bib may only be transferred to another team member at the timing mat.
