San Antonio Marathon Course Details

The Rock 'n' Roll San Antonio Marathon offers a thrilling 42.195 km (26.2 mi) journey through the vibrant streets of San Antonio, Texas. Runners will navigate a dynamic mix of flat stretches and rolling hills, with an elevation gain of about 533 feet, making it a test of endurance and strategy. The course kicks off and concludes in the bustling heart of downtown, enveloping participants in the city's urban charm.

Expect notable inclines, particularly the climb between kilometers 10 and 11, and the steeper ascent from kilometers 32 to 33. These are balanced by exhilarating downhill sections, like the descent from kilometers 26 to 27, demanding careful speed control to protect the joints. As you traverse the city's diverse landscape, the urban backdrop provides a stimulating environment, though the elevation profile requires a thoughtful pace adjustment, about 1.4% slower than a flat course.
