At least for St. Louis, the number of half marathon finishers keeps decreasing. In 2011 there were over 17,000 finishers. In 2015 there were just over 8,000 even after they offered a Living Social deal. Early this year I received an email stating that I would get a commemorative bib and bottle opener key chain if I ran it one more year to make it five in a row. And so....I ran it one more year and now post-race I can honestly say that this was my last year running the Rock 'n' Roll in St. Louis.

Remember when we used to get the black bags stamped with the Rock 'n' Roll logo for that particular city? Well those days are over apparently over! The shirts were still cute this year, but the commemorative 5-year bib and key chain took stops at three different booths before I was finally directed to the correct staff. Even during the race, several runners asked where I got my 5 Years Running bib because they never found where to pick it up at the expo.

I still love the course since it takes you through so many historic neighborhoods and volunteer support was great, but I think race is just losing its' luster.

I didn't see any other reviews for 2015, so I thought I would be brief and add mine.

Same in 2015:
Great expo at Chaifetz Arena - I am biased because I work at the expo every year, but I heard many comments about how quick and easy it was.
Same great finish line food, featuring local eateries and a wide range of salty and sweet treats.
Great volunteer support and crowd support.

New in 2015:
New course brings you over two different bridges into Illinois and back. Safety tip: I would advise against running on the shoulders of either bridge. Believe it or not, you could feel the bounce of the runners on both bridges and another runner in my training group and I almost fell coming back into Missouri because the bouncing bridge nearly caused our legs to buckle underneath us. We both stopped and walked if off, but just a warning. The feeling of the pavement bouncing under your feet was very bizarre and more pronounced on the shoulders of the road.
The t-shirts were gender specific but we had MANY complaints that the women's shirts ran very small.
I believe the course was flatter this year, but I used the word "flatter" and not "flat." I live in the St. Louis area, yet I forget how hilly downtown really is.
The welcome squad as we crossed into East St. Louis was probably my favorite along the whole course.

I said I would be brief, but overall I would recommend the race for both locals and out-of-towners.

Other runners have gone into more detail, so I will just quickly list pros and cons.

Pros:
If you stay downtown, the start/finish and expo is easily walkable.
Great expo
The race shirts were unique with the Indy skyline on the back
Personalized posters with all runners names printed in tiny font
Finisher's hat
Medal is part of a four-year series but they are still great even if you run it only one year
Scenic course
Great spectator support
Two minor hills
GREAT and plentiful post-race food

Cons:
One of the first water stops was out of water when I arrived
Some sections were very congested between cars parked on the streets and runners
