Zappos.com Rock ‘n’ Roll Las Vegas Marathon and half Marathon, to benefit the Crohn’s & Colitis Foundation of America, will once again gather some of the best athletes and runners in the nation and other countries around the world  for its second annual event set to take place on Sunday, December 5th on the world famous Las Vegas Strip.

This year's race will feature a few adjustments to course. The race will kick off in front of the Mandalay Bay Resort and Casino and will head north on Las Vegas Boulevard all the way to the El Cortez Hotel and Casino, in Downtown Las Vegas, where runners will switch over to the southbound lanes and head back down the Strip.

The entire ½ marathon course as well as the first 12.6 miles of the full marathon course will be on Las Vegas Boulevard. The full marathon will split from the ½ marathon west at Mandalay Bay Road/Hacienda until just past Jones and back while the ½ marathoners continue to the finish line in the Mandalay Bay Resort's parking lot.

In addition to the athletic competition, the Las Vegas Marathon will feature live bands, including a live performance by Poison's former lead vocal Brett Michaels, as well as themed water stations and cheerleaders along the flat and fast course.   The traditional Run-Through Wedding Chapel will also continue at a new location at the Venetian Resort, where participants can get married or renew their vows overlooking the Las Vegas Strip with thousands of running witnesses.

This year’s Zappos.com Rock ‘n’ Roll Las Vegas Marathon will host a Health & Fitness Expo presented by Power Balance and held at the Sands Expo and Convention Center.  The Expo will be free and open to the public beginning Friday, December 3rd from 11 am to 7 pm and on Saturday, December 4th from 9 am to 5 pm.  The Expo will feature the latest health and nutrition information with a variety of products for sale and sample as well as offer free fitness related clinics.

“The Zappos.com Rock ‘n’ Roll Las Vegas Marathon proved to be a big economic boon for Las Vegas last year and with the race course changes being implemented this year, it gives us the capacity to expand the number of runners who can participate.  We are thrilled that this event continues to grow and bring even more visitors to Las Vegas” said Pat Christenson, President of Las Vegas Events.
