The Rock 'n' Roll Pittsburgh Half Marathon has been postponed from August of this year until an undetermined date next year after the CIty of Pittsburgh rejected the race organizer's special event permit application.
Acting chief of emergency medical services Mark Bocian said the permit application was denied because of concerns about the heat for the Aug. 4 race date.
In a statement, the Competitor Group, which puts on the Rock 'n' Roll race series, said "We can no longer plan and take registrations for an event without the support of the mayor's office, director of public safety and the special events committee necessary to organize a world class half-marathon on the agreed upon date of Aug. 4, 2013."
About 4,000 runners had already registered for the event, half of whom were coming from out of town. Runners will have the option of registering for another Rock 'n' Roll race in another city or will get a refund.
When the event was announced in March of 2012, VisitPittburgh estimated the event could fill 5,000 local hotel rooms and pump $8 million into the Pittsburgh economy through hotel, restaurant and related spending.
