This was my third Vegas rock and roll -- last year I ran the full and had a terrific experience. The year prior I ran the half. I was so excited -- elated, actually -- about the opportunity to run a race on the Las Vegas Strip at night for the first time. A friend ran with me - which was great because we were able to navigate and dodge some of the crowds (before/after/during) together. I had a strong run, but found it to be really chaotic. WIth the increased number of runners, plus volunteers, plus supporters, plus tourists and many events in town the same evening/weekend those running (and race organizers) faced some surprises. In all fairness, big crowds sometimes make me a bit crazy and running at night and running in the cold isn't really my "thing." I feel strongly that the opportunity to run at night in Vegas is unmatched and also feel confident that based on feedback received, the city and the race organizers will do what it takes to make necessary improvements and this will be a much better experience for everyone running in 2012. Huge races like this are exciting and can be fun, but some runners are better suited to (and enjoy) smaller races.
