A running event in Savannah is on pace to become Georgia's largest marathon and half-marathon.

A spokesman for the national Rock 'n Roll Marathon group says, about 20,000 people so far have registered for the November event.

The spokesman, Dan Cruz, says the running event is expected to sell-out at 23,000 people.

"The largest running event in Georgia is the Peachtree Road Race," Cruz says. "That has 50,000 runners."

The Road Race, in Atlanta, however, is 6.2 miles. A marathon is 26 miles.

Distinctions aside, the number of participants is extremely important for Savannah business officials.

They're expecting a huge boost from hotel, restaurant and other spending associated with the event.

So far, about 6,000 people have registered for the marathon, while about 14,000 people have registered for the half-marathon.

Rock n' Roll Marathons are held in several cities across the continent.
