(Las Vegas, NV) — Organizers of the Rock ‘n’ Roll Las Vegas Marathon are making some changes for this year’s race. The full and half-marathon will still begin on the Strip, but will cover more of downtown Vegas. The finish line for both events will be outside Caesars Palace. About 38,000 runners took part in last December’s marathon, which was criticized for overcrowding and water quality at rest stations. A professional firm will hand out water and Gatorade along the course.
