Cary, N.C. — Thousands of runners set out Sunday morning to take part in North Carolina's biggest marathon.
The Tobacco Road Marathon is a whopping 26.2 mile trek through the Tobacco Road Trail, though runners can also opt for the 13.1 mile half marathon option.
According to officials, about 13 percent of the runners in the event qualify for the iconic Boston Marathon.
An estimated 4,000 runners started their journey at 7 a.m. at the trail at Cary's Thomas Brooks Park, where they'll run until the marathon ends at 2 p.m.
Anywhere from 6,000 to 8,000 spectators and volunteers are present at the event, organizers said. The event draws runners from more than 39 states.
All proceeds from the marathon go to local charities. Officials said that, so far, the tradition has raised $631,000 for various organizations, and $1,000,000 is expected to be raised by 2019.
