A growing social network is driving information about the Country Music Marathon.  You can now go to MySpace, Facebook and Twitter to get race info and share training tips for next Saturday's race.   Marathoners have been wearing microchips for years, that allow family and friends to track their progress during a race.  This year, the race features a tent with more computers so your team can get immediate results.  It's also handy when they need to find you after the race.  It won't be long before a marathoner figures out how to tweet while running the race.  Just imagine the post:  mile 21. feet hurt. send ambulance.  
 
Some runners are posting training vlogs on YouTube. Catch the hula hoop action as these runners take off.
