About the New Year's One Day
The course is a loop around Cottonwood Lake in Hellyer Park, run on an asphalt path that stays flat the whole way around. You come back past the same point again and again, so you can run through the night or step off whenever you have had enough. The format is timed rather than distance-based, which draws a different crowd than a typical road race.
Check-in opens race morning at the Buena Vista Pavilion in Hellyer Park. Plan to arrive a bit early to get your bib before your event starts. Parking requires exact change at the gate, so have cash ready before you pull in.

Finish-Time Stats
Going by the 2025 results, this is a small, friendly field, and the spread of finish times is wide, so this is a mostly recreational race rather than one for club runners.

The New Year's One Day has been held every year since at least 2021. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
