The Rock ‘n’ Roll Las Vegas Marathon and surrounding events will take place as scheduled on the weekend of Nov. 12, but there will be changes to the course after the Oct. 1 mass shooting on the Strip. “The marathon and half marathon start line and start-line festival concert location will change, but will still take place on the Las Vegas Strip,” organizer Dan Cruz said. The prerace concert was originally scheduled to take place at Las Vegas Village, the site of the shooting that left 58 dead and almost 500 injured, while the start line was located near Mandalay Bay.
