Not a very big race, contestants wise, but organizers did a good job overall. Weather was interesting as Tornados hit night prior and raceday was quite cool but organizers did good job clearing course of debris. Course was scenic and enjoyable. Post race was so-so

The first and last few miles were around the lake nice and flat The rest of it had rolling hills not too bad overall fairly flat. It was very cold and windy but it was sunny and we beat the rain.
Small, cold, but great experience

Temps were in the teens with a wicked wind, but I still had a great experience. I found a great pace group that helped me get to the finish line. The hills weren’t as bad as they appear- coming from Cincinnati/NKY I’m used to climbing. Loved running around the lake and finishing with a green beer.
Pleasant race outside of StL

This was a pretty smooth, easy race about 25 minutes away from downtown StL. The scenery was OK throughout and especially pretty for the first and final 2 miles while near the lake. There is some amount of gentle ups and downs especially with a couple bridge crossings, along with one major hill that I walked up. The aid stations were plentiful with Gatorade and water, which was frozen on top because it happened to be an extremely cold race day. I wish they’d make it more clear that you can easily drop someone off at the start; we’d been unsure beforehand and it turned out to be no problem. The medal was ok but not my favorite design; the shirt was nice!
Run over the Missouri River and back

The 2019 event was postponed one day from Saturday to Sunday by the threatening weather; the communication from race organizer Missouri Runs was good. They set up another packet pickup on Saturday, which was helpful since the first pickup was 11-5 on a Friday.
Swag included a pint glass and quarter zip tech pullover. The finishers medal was cool as well.
Race parking was limited in the park. Shuttle service from the Family Arena parking lot across the river in St. Charles arena was smooth and efficient.
The course starts and ends around the lake in Creve Coeur Park, follows a paved path toward the Missouri River, crosses the river and covers a brief section of the Katy Trail, then comes back on largely the same route (but a different side of the lake). The course’s biggest hills are the approaches to the bridge on both sides of the river. And there is an uphill around mile 2 leaving the park and getting into the bike trail, which is a downhill for mile 11 or so. Otherwise, largely flat.
The weather ended up perfect on race day. A little wind was blowing from the west, particularly noticeable at the end, running the last quarter mile or so on the north end of the lake.
Adequate aid stations on the course and I believe there were race photographers but otherwise not many people along the course. The only place for spectators other than the park is a parking spot near the Katy Trail in St. Charles County. But this is a good course to take in the scenery in the flats running toward the bridge and then crossing the river.
Great race in bad conditions

This was a great race around Creve Coeur lake in a suburb of St. Louis. The half marathon course starts at the lake and goes to the Missouri River and then down to the Katy trail and then back. It is pretty flat except going from the Katy Trail back up to the bridge to cross the Missouri River. The volunteers were great. Swag-wise, you get a Tshirt, cookies (That were amazing), free beer, a pint glass (Would be better if they would put the beer in the pint glass), and a medal. The only negative is that I wish they would start the 7K either earlier or later than the half marathon so that when the transition comes, you don’t have to get behind those that are turning.
