Austin Marathon

The Austin Marathon (officially the Ascension Seton Austin Marathon, Half Marathon & 5K) is one of those races that feels like a citywide block party that just happens to include a timed 42.2 km tour through the heart of town. It’s held on Austin streets with a downtown start and finish area, and the vibe leans hard into what people associate with Austin: energy, crowds, music, and a “locals + visitors all in one big weekend” feel. 

Runners typically get a course that shows off a bunch of the city’s most recognizable areas, with spectators packed into key stretches and a big finish-line festival atmosphere. The weekend is structured like a proper race festival too, with an expo and plenty of pre-race logistics built around making it easy for out-of-towners to plug in, pick up packets, and treat it like a mini trip.
