The annual ING Miami Marathon and Half Marathon generated $52.2 million in total economic impact for the city of Miami and Miami-Dade County in 2012, according to a study by Temple's Sport Industry Research Center. The economic impact of the Miami marathon increased 26.3 percent from the 2011 event, according to the study. The increase is attributed to a rise in individual spending by international visitors and an increase in the number of non-local participants.
