Endurance events like San Diego’s Rock 'n' Roll Marathon and Carlsbad’s 5000 meter race generate significant economic benefits to the county, according to a new report from the National University System Institute for Policy Research, a think tank based in Torrey Pines.

NUSIPR compiled a data base of more than 100,000 participants in 66 local endurance events from last year, and found that more than one in three or 34 percent were visitors from outside the county.

The report states that the endurance events here last year generated a total economic impact of $64.1 million. The events supported $23.1 million in wages and 583 direct, indirect and induced jobs, the report states.

The biggest endurance event and the one having the most economic clout is the Rock 'n' Roll Marathon, which drew 24,642 runners last year. The next two largest events were the World Famous Mud Run, with 20,000 participants, and Father Joe’s Villages Thanksgiving Day 5K, with 10,000 participants. The next seven events ranged from 8,472 to 4,556 participants, many of them coming from nearby California counties, but a sizable number also coming from out of state and outside the country, the report said.

“With a warm climate, numerous lodging options and a year-round schedule of events, San Diego is positioned to become a leader in sports tourism,” said Vince Vasquez, NUSIPR senior policy analyst.
