SACRAMENTO (CBS13) – The women’s fitness festival is happening this weekend without one popular race. The half marathon was canceled after Union Pacific railroad denied organizers safe passage over its tracks.

The Sacramento Running Association, which organizes different events, including the California International Marathon (CIM), says the railroad has new policies after incidents with other events around the country.

“I think there’s an importance to having that and Union Pacific recognizes this is an important event to our city. And that’s very different than how maybe they’re gonna evaluate smaller events,” said Sacramento Running Association Executive Director Scott Abbott.
