La Llorona 10K Trail Run

La Llorona 10K Trail Run is held in San Antonio, Texas, on January 24, 2027, with the single 10K trail race starting at 9 a.m. There is one distance and one start, so the day is built around a single event rather than a stacked program.

A trail 10K is one of the most useful races on a runner's calendar. It is short enough to attempt without a long specific build, but the surface slows you enough that road pacing simply does not transfer, which makes it a good lesson in racing by effort. If it is your first time off pavement, run the opening mile deliberately easy and let the terrain teach you where you can push. Runners with road speed already banked can treat it as a hard hour that builds strength for a spring half marathon or marathon.
