For over 20 years, the Rock 'n' Roll Marathon Series has made running fun by infusing each course with live bands, cheer teams and more. The pinnacle event of the series, the Rock 'n' Roll Las Vegas Marathon & 1/2 Marathon, is the biggest and best night running event in the world. The busy Las Vegas Strip closes to traffic once a year for the 35,000 r participants from around the world to have a one-of-a-kind nighttime experience complete with music, lights and entertainment stationed along the course. The marathon and half marathon races start near MGM Grand and pass by all the must-see Vegas sights including the iconic 'Welcome to Las Vegas' sign, Paris Hotel's Eiffel Tower, and the Fountains of Bellagio, before finishing at the foot of the Mirage Volcano. The on-course experiences in Las Vegas are endless and unique, including a Run-Through Wedding, where hundreds of pre-registered couples get married or renew their vows during a group ceremony and then run to the finish line together as newlyweds. Notorious for its impressive medal designs, the event is more than just a race, it's a running and entertainment festival weekend. Exclusive runner perks, parties and entertainment are offered all weekend long including a pre-race headliner concert that has previously featured The Goo Goo Dolls, Kid Rock, All-American Rejects, Macklemore & Ryan Lewis and Snoop Dogg. This year, Kesha will take the stage after the Saturday night 5K as the event's first female performer.
