About this race
Lace up and show up. The SHEATH race is back — and this year we've gone bigger, adding a 10K for anyone ready to push past their limits.
Whatever your pace, shape, or size, this is your race. Chase a new PR, walk it with your crew, or just come out to move, sweat, and celebrate what your body can do. Every level belongs on this start line.
SHEATH Underwear is a veteran-owned, family-run activewear company built on one simple idea: when you feel good, you perform better. We're bringing that philosophy off the shelf and onto the course — a morning of miles, music, food, and community, powered by the strength inside everyone who shows up.
Why We Run:
We believe every challenge can be conquered — on the course and off it. This race is our way of bringing San Antonio together to honor peace, resilience, and the quiet strength it takes to keep going. Cross the finish line for yourself. Cross it for your community.
