San Antonio New Year's Eve 5k

San Antonio New Year's Eve 5k is run in San Antonio, Texas, on December 31, 2026, starting at 6:00 p.m. The single format is a 5K (3.1 miles) on a course billed as fast, with playful competitions for individuals and for teams. The first 100 adult runners receive a special jacket and everyone else gets a long-sleeve shirt, and every finisher takes home a New Year's clock medal.

A flat, fast 5K on the last evening of the year is a natural place to chase a personal best. If that is the plan, keep the last few days easy, warm up for 15 minutes with a handful of strides, and go through the first mile at goal pace rather than above it. The team scoring also makes it an easy race to talk a running group or a family into, and the evening start leaves the whole day free before you line up.
