Prepare for Austin Marathon

A plan built from your answers and your race date.

The Austin Marathon is run in the Texas state capital, on a city course that moves through downtown and the neighborhoods around the Capitol and the lake. Austin sits at the edge of the Texas Hill Country, and the route reflects it: rolling grades rather than long flat stretches. The atmosphere is that of a major city race with strong crowd support along the way.

Three distances share the same morning, marathon, half marathon and 5K, which makes it easy to travel as a group with different goals. com before booking anything.

The formats

3 formats on the program.

Format	Distance
Marathon	26.2 mi
Half Marathon	13.1 mi
