Cheer on the 22,000 runners fighting cold and fatigue in the Chevron Houston Marathon as they head out as early as 6:45 a.m. from the George R. Brown Convention Center on a course that will take them west down Memorial Dr. past 610, around the Galleria, through West University, past Rice, up Montrose to the Heights and back down to the starting point.

Or get inspired (runners raised over $1 million for different charities in 2009) and sign up for the 2011 race.
