Nike has become the official brand partner of the San Antonio Marathon, whose second annual race weekend is set for December 4 through December 6. Registration for the 5K, half marathon, and full marathon is open now, and runners in the San Antonio area and beyond can sign up at sanantoniomarathon.com.
Why it matters
A major brand partnership signals that the race is growing into a larger fixture on the running calendar, which can affect registration competition, travel planning, and the local running community. For San Antonio runners, the event's scale also means the weekend will bring heavier traffic and hotel demand.
The inaugural 2025 race sold out with 18,544 registered runners and was estimated to generate $22 million in economic impact and fill nearly 11,000 hotel room nights. These figures come from the event's own reporting, and the source does not provide a projection for the second annual race.
The players

Health Landscape
The inaugural 2025 San Antonio Marathon's sellout of 18,544 runners shows how organized mass-participation races can draw large fields in a single city. Its second-year sponsorship by Nike extends that pattern and makes the event part of the broader running-event market in Texas.
If you are considering a 5K, half marathon, or full marathon this December, the race registration page at sanantoniomarathon.com lists the available distances. Anyone planning a longer race should talk with a physician about a training plan suited to their fitness level.
The takeaway
Mass-participation races are drawing large crowds to cities like San Antonio, and sponsorship deals like this one reflect that growth. If you plan to race, check distance options early and ask your physician about training appropriate to your fitness.
What happens next
The second annual San Antonio Marathon race weekend takes place December 4 through December 6, 2026, with the 5K, half marathon, and full marathon.
