Southtown River Run [10k]
About this race
Start your year off on the right foot and join us for a chill 10k along the San Antonio River. We’ll have everything you need to fight those excuses and get moving: DISTANCE (10k effort!), COFFEE, HYDRATION, MUSIC, PRIZES, and SMOOTHIES! There will also be space to connect and hear inspirational stories from people who have pushed through trials to accomplish their goals, so we can motivate each other and set the tone for 2026.
Joining a group run goes beyond how fast and how far you go – it's about showing up and being encouraged by the people who have chosen to be a runner that day. For some of us, getting up early on a cold morning will be the challenge, and for others, it’ll be going the 10K distance. In either case, embrace the challenge and let's make some fun of it!
