Training for the Austin Marathon means training on Austin's actual terrain, and the good news is the city has real variety within easy reach of downtown — flat lakeside miles for recovery days, technical trail running for a change of surface, and genuine hill work if you want to prepare for the marathon's climbs specifically. None of these are the race course itself; they're the routes locals actually use to build fitness year-round.

Lady Bird Lake Trail: the city's default run

Officially the Ann and Roy Butler Hike-and-Bike Trail, but almost universally called the Lady Bird Lake Trail or Town Lake Trail by locals, this roughly 10-mile loop circling Lady Bird Lake is Austin's signature running route and the default choice for a huge share of the city's runners and run clubs. It's mostly flat and well-shaded, crosses the water at multiple points including the Pfluger Pedestrian Bridge and the Congress Avenue Bridge — home to a well-known bat colony — and offers several shorter loop options if you don't want the full distance. If you only run one route while you're in Austin, this is the one locals would point you to first.

Barton Creek Greenbelt: for trail runners

For a genuinely different surface, the Barton Creek Greenbelt starts near Zilker Park and runs southwest along Barton Creek on rugged, rocky limestone trail — Austin's best-known trail running destination, with creek crossings, technical footing, and a legendary finishing climb known locally as the Hill of Life. It's accessible enough for an easy out-and-back if you're new to trail running, but experienced enough runners use it for genuine hill and technical-terrain training. Trail shoes are worth the extra bag space if you're planning to spend real time on it.

Shoal Creek Trail: for easy, shaded miles

Running north from downtown along Shoal Creek, this mostly paved trail offers a flatter, quieter alternative to the busier Lady Bird Lake loop — a good choice for an easy recovery run or a shakeout jog without fighting crowds. It connects into a broader network of Austin trails, so it's easy to extend into a longer run if the mileage calls for it.

Mount Bonnell: for hill training

If you're specifically training for Austin Marathon's climbs, a route out to Mount Bonnell is the most direct way to simulate real hill work: starting from the Lady Bird Lake Trail, it follows Lake Austin Boulevard and Scenic Drive out to Covert Park at Mount Bonnell, one of the city's best-known high points, finishing with a short, genuinely steep climb to the summit. It's a longer out-and-back commitment than a lakeside loop, but there's no better way in Austin to get your legs used to sustained climbing before race day.

A few more worth knowing

• Walnut Creek Metropolitan Park, in north Austin, offers smoother, more beginner-friendly singletrack trail if the Greenbelt's rocky sections feel too technical.
• Zilker Park sits at the crossroads of several of these routes and makes a natural starting or turnaround point if you want to combine a lakeside loop with a taste of the Greenbelt.
• Downtown and the UT campus make for a shorter, scenic route on their own — straight up Congress Avenue to the Capitol and through campus past the UT Tower — good for an easy shakeout run during marathon weekend itself.
