How fast is it?
About average for Nevada 5Ks
The fastest quarter of the 2026 5K field finished under 29:51, against 30:26 in a typical Nevada 5K, so times here are about average.
- 10K: Slower than most US 10Ks. The fastest quarter of the 2026 10K field finished under 1:03:18, against 55:00 in a typical US 10K, so times here run 15 percent slower.
Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.
Typical race-day weather
Around January 3 the day usually runs from 40°F at dawn to 54°F in the afternoon, with measurable rain on about 11% of days. Cold snaps dip to 34°F and hot years reach 60°F.
Based on 75 days within a week of the date over the last 6 years, from historical weather for the start area. Not a forecast.
