The Rock 'n' Roll Arizona Marathon is a marathon held annually in Arizona on the Sunday before Martin Luther King, Jr. Day that links three cities of the Phoenix Metropolitan Area: Phoenix, Scottsdale, and Tempe. The marathon race can be used to obtain a qualifying time for the Boston Marathon. The race weekend also includes a half marathon, a 10K run, and a 5K run. The competition attracts tens of thousands of runners each year; more than 32,000 competed in 2010. The prize money for winning either the men's or the women's marathon race is US$1,000.
