Ran across this today:
Organizers Canceled the Hilton Head Marathon Just 2 Weeks Before the Race. They Never Had a Permit
The Hilton Head Marathon & 10K/5K organizers canceled everything two weeks prior, citing unforseen issues with safety and other concerns.
In reality, they didn't have permits from local law enforcement that was concerned on multiple issues regarding safety. No permits = no official ability to put on an event, be on major roads, safety, etc.
"Ventures Endurance" puts on the marathon and is owned by Gannett. It also does the Hot Chocolate Run series, Statesman Cap10K in Austin and Milwaukee Marathon.
