If you are looking to hunt a Personal Best or want the adrenaline of a closed-course city marathon, look elsewhere. This is a low-stakes, high-vibe social outing designed for people who want to move without the ego of a stopwatch. It’s essentially a guided group run with a medal at the end.
Sloth Run SAN Antonio 2026 takes place on Saturday, June 20, 2026, in San Antonio, United States. You can choose from a 13.1 Half Marathon, 10K, 5K, a 1-Mile Family Fun Run, or even a Virtual option. It is a relaxed, non-competitive event held within the greenery of Olmos Basin Park.
Should I prepare for extreme heat?
Yes. You are running in San Antonio in late June, which is a recipe for humidity and high temperatures. Even with a 7:30 AM start, the Texas sun is unforgiving. Don't attempt this without proper hydration strategy and lightweight, breathable gear. This isn't a race where you can "tough it out" without respect for the climate.
What are my distance and timing options?
You have the full spread: 13.1, 10K, 5K, and a 1-mile family dash. The waves start between 7:30 AM and 8:30 AM. If you are a slow mover—which is the whole point here—don't sweat the clock. The organizers stay out for about three hours after the first wave, so there is plenty of breathing room for those of us who prefer a "sloth" pace.
Is the registration fee a good deal?
For the price point, it’s an absolute steal. At $42 for a 5K and $50 for a Half Marathon, you are getting a shirt (shipped to you), a medal, and a finisher towel. Most "serious" races charge double that for half the amenities. It’s priced for accessibility, not profit.
What should I expect from the course and organization?
Don't expect a massive festival atmosphere or heavy-duty race infrastructure. There are no closed roads and no timing chips, so you'll need to track your own progress via Strava or your preferred app. The course is guided by coordinators through the park rather than a sea of barricades and signage. It’s minimalistic, which keeps the vibe chill but means you shouldn't expect a high-tech race experience.
What do I get for crossing the finish line?
You’ll walk away with a finisher medal and a towel or giveaway. You can also access your digital certificate and results via Thebestraces ↗. If you want to join the community afterward, the event provides access to local run clubs.
