07ESBRU01.jpgUnless you’re participating in the Empire State Building’s “Annual Run Up” race this Tuesday, it’s advisable to avoid the iconic landmark at all costs. Between the hours of 9-11AM, hundreds of runners will take to the lobby as they race up 1,576 steps to the Observation deck on the 86th floor. Managers are asking tenants on the ground floor to lock their doors, warning that this “event will cause the corridor to become quite congested” and access will only be available at the 34th St. entrances. Great, so now where are the delivery guys supposed to wait? Full warning after the jump.
