Making a Vacation of It: Chicago Tourism
Chicago's Rock 'n' Roll half marathon offers great sightseeing, winding past landmarks like Soldier Field and the Chicago Theater. It draws more than 20,000 people -- some runners, some walkers, some spectators. Whether cheering or racing, all get to enjoy the local music of the Windy City. A couple of dozen different bands along the route, including Party Freak, M&R Rush, and the Chicago Mob Dixieland Jazz Band, in 2011, play the marathon concert.
There's a 3.5-hour time limit, but slower runners and walkers can catch a ride part of the way so they can finish -- and take home the commemorative medal.
Admission to the big concert is free, and the race benefits the American Cancer Society.
