Charity Partner: The Stars and Stripes Half, 10K, and 5K is proud to support the San Marcos Lions Club through proceeds from the race and individual donations made during registration.
100% of all donations will go directly to support Texas communities impacted by the devastating floods of July 4–6.
The San Marcos Lions Club works hand-in-hand with local Lions Clubs across affected areas and applies for international-level grants to maximize both funding and volunteer support where it's needed most.
