If I could give them no stars, I would. It was so poorly organized and mismanaged. I will never run another RnR. The Vegas run was so bad -- people couldn't get to their proper corrals so faster runners were having to navigate around walkers and really slow runners. Talk about greed -- they doubled the capacity and this is the result. I second what others are saying -- felt like cattle. And to top it off, there was no possibility for a PR because of the pile-up of runners at the finish. They decided to have the medal distributors 10 ft. from the finish and there were so many people crossing that I came to a dead stop about 20 feet from the finish line. Unbelievable. The scene in the Mandalay Bay was scary. Couldn't get to gear check. My sister was supposed to run but wasn't feeling well in the smothering crowd. She threw up and was so sick she couldn't run, so she took my stuff.  I thought the San Diego RnR was bad with their horrific traffic back-up, lines that go on forever, making you walk over a mile to your car or stand in line for over an hour to get on a shuttle -- waiting and more waiting. I said I'd never do another Competitor Group race again. Now that is final. The Surf City Marathon in Huntington Beach is the way to go. What an amazing job they do. Seamless organization, beautiful course with ocean views. The weather is great. They know what they're doing.
