DON'T DO THIS RACE!!!!!!!!!!!
I did this race last year and had an amazing experience. This year...not so much.
They expanded the race from 20k to 45k but put NO THOUGHT into how the extra numbers would affect the race. Last four miles there was NO water left, several miles there was no lights (in the sketchy area of Las Vegas off the strip) and then after the race NO ONE was directing traffic in the Mandalay Bay so took more than 90 minutes to exit. On top of that many food places closed at 10pm so no food. I felt like I was on the Titanic-people passing out to my left and right from dehydration and no food, wall to wall crowds....
Next year they plan to expand to 60k....I will not be there!!!!
