When the marathon course merged with the 1/2 marathon course, marathoners were forced behind 1/2 marathon walkers.

Out of the 41 marathons I have completed, this was the worst 2nd half of a marathon course I've ever experienced.

My advice: Stay away from this one until the race organizers fix their mess!

Run, don't walk, away from this race!! Everything everyone has said is true. Complete disregard for runner safety and experience, complete money grab. I can't say a single good thing about this race (other than the 4 pm start time). The worst was the tiny marathon lane that ended for much of the second half and the dodging that caused me to lose at least 15 minutes off my time and killed my IT band. WILL NEVER RUN ANOTHER ROCK AND ROLL RACE.

I flew 2,000 miles for the absolute worst marathon experience I have ever had.
The lack of organization was absolutely astounding. Water was lacking toward the finish, you had to dodge walkers constantly during the 2nd half, the finish line area was a disorganized mess, and I will NEVER enter a so called 'Rock & Roll' event again.

The race director? Was there one? Absolutely horrible event. You people should be ashamed of yourselves for subjecting the participants to such deplorable and potentially unsafe conditions. Every runner deserves a refund of their entry fee, and then some. Shame on you, Competitor Group....shame.

Ran out of water last four miles, 90 minute bottle neck at finish line, shoulder to shoulder people-and they want to increase it by 15k next year!!!!! Worst experience ever, and I have done more than 20 halfs. Boycott RnR!!!

No organization, poor planning for both the race and the expo, not enough volunteers,no medals, no information, the debacle at the Mandalay Bay after the race..the list goes on and on. An absolutely terrible experience. I will NEVER run an RnR event again. Save your money and choose another event until RnR no longer handles this race.

I have run many full and half marathons and this is by far the worst organized I have ever been part of. From the expo to the actual race this was a complete nightmare for runners whom no consideration was given to before, during or after the race. This was a lesson in how 'not to' organize an event. I concur with all comments made on this marathon on this posting. This was a very expensive race and 45,000 runners a lot of profit was made and little or no courtesy paid to the consumer. I and the runners I travelled with will never run a Zappo's organized race ever again.

OK... my first 1/2 Marathon ever. It was an amazing personal milestone & achievement inspite of how *POORLY* it was organized & *DANGEROUS!!* it was.

My advice to everyone... *STAY AWAY!!* from this race until they figure it out.

I was in the post-race Mandalay Bay gauntlet of people for almost 2 hours. Imagine the Willy Wonka scene where they are all trapped in the little room and looking for the door to get out. Now layer onto that scene a bunch of overheated, and exhausted runners up way past their bedtimes. One man came tumbling through the crowd saying he wasn't feeling well, trying to get out & he passed out, fell backwards, and smacked his head on the concrete with a very loud thud. We screamed 'MEDIC!' for what seemed like ages. Finally security came, and said they were going to call for help from the nearby Starbucks. As the sea of humanity continued to glacially move forward, I saw another 3 people down waiting for medical attention. Once I finally got to the front, I saw the LVFD paramedics treating a couple of people. I begged them to work their way back into the crowd since there were others who were untreated & in a more serious condition.

The expo was attrocious... the line of cabs to the Sands was at least a mile long. I found parking at Harrah's, and snuck in & out through the delivery area into the Expo & Check-In.

For the day of the race, the directions for where to park upon race start was a *JOKE*! Thank the Lord for Smartphones & the Google Maps real-time traffic API. I was able to navigate the streets of LV and see the traffic on streets change from green, to yellow, to red, and avoid wasting a *ton* of time.

Post race, I was disappointed that the race officials sent a message asking for feedback, but that I had to give all my financial information to 'help' them determine financial impact to the region.

I wouldn't do it again even if RnRLV offered to pay for my entry, hotel, etc...

Be afraid of this race... be very afraid.

I don't have any disagreements with the complaints listed below. It was very poorly organized, and I feel like I was completely ripped off.

The one thing I will add is that I inquired with one of the Team Challenge leaders about why their participants (mostly leisurely walkers) were in corrals paced for a 2 hour finish time. He told me that Competitor Group wanted all charity participants in corrals 17 - 19.

Why in the world a professional race organization would cram 8,000 people moving at a pace to complete in 4 hours in front of 20,000 people moving at at pace to compete in about 2 - 3 hours is completely beyond me. It's completely disrespectful to those of us trying to move at our normal pace. Weaving between orange shirted Team Challenge members walking 3 and 4 people across at a pace that would be too slow for my 80 year old Grandmother for the first 12 miles was completely frustrating. I was never able to relax and enjoy the race, because I was constantly looking for ways around people. Competitor Group is 100% responsible for this.

I won't do another Competitor event. This is basic race logic. Horrible, horrible race management.

1- almost threw up after the race and a fellow runner threw up multiple times. we don't know the cause yet.
2- race went thru seedy parts of town where there was no security or police presence
3- start corrals- we went to the wrong side and had no idea we were so far from our corral and had to walk thru multiple corrals to get to the right one
4- too many runners- we almost got ran over.
5- no gatorade on the course
6- very limited water and the water tasted odd
7- the inside of the Mandalay Bay was horrible packed- it was a huge cluster. People couldn't move. Thank goodness there wasn't a fire.
8- I didn't get a medal at the finish and I still don't have the medal that was supposed to be mailed to me.

very disorganized, much too big, little presence of staff. Unsafe and scary- seeing people fall and collapse... the whole experience was poorly run- from expo, to race, to post race food, gear check
