Runners rock past the Alamo during 2008's Rock 'n' Roll Marathon in San Antonio.

It's rare to see a runner without a pair of headphones these days. But you'll see plenty of empty ears during next weekend's Rock 'n' Roll Half-Marathon, because the course will be full of musical entertainment, from the starting line village at Columbus & Congress to the waterfront bikepath near 31st avenue. Local acts include Jeff Manga, Boho Paisley, Thinner Teed and more.

Even if you're not running (the August 2 event is sold out), this event offers a chance to see musicians awake well before their usual rousing time (the first set begins at 6:30 a.m. in Grant Park). And of course, you can cheer on all the people who are participating, including two-time 5,000-meter champion Kara Goucher, who will have cameras on her throughout the entire race. Make sure to stick around for the post-race concert at 10:30 a.m. in Grant Park, headlined by blues vet Susan Tedeschi.
