The Livestrong Austin Marathon and Half Marathon is fast approaching.

About 20,000 runners and 30,000 spectators are expected to show up for race, which Austin Marathon race director John Conley said creates a feeling so great that you wish you could package it up and sell it.

The race begins Sunday at 7 a.m. You can volunteer or find out about road closures by clicking here.
