FI and I just signed up to do the half marathon again in Vegas! We did it last year for the first time and it was so much fun!
I highly recommend it for anyone who likes to run or walk. The half time limit is 4 hours and there were a lot of walkers. It's so fun to be able to walk on the strip at night! It's really cool to see the strip from a different vantage point like that.
Also, good to keep in mind these dates for any November brides, the strip is shut down on Sunday for the race and it brings in a lot of people. Traffic is insane that day.
