FREDERICK, Md. (AP) — Organizers of a problem-plagued, military-style endurance race in Frederick say they’re offering refunds or other compensation to thousands of people after the weekend event was cut short.

Frederick Police Chief Kim Dine told The Frederick News-Post Sunday that organizers of the Mid-Atlantic Tough Mudder didn’t stick to their traffic plan. He says they weren’t prepared when 20,000 people showed up Saturday for what was to have been a two-day event.
