I wasn’t able to get in the night before so they fortunately have early morning bib pick up BUT pay attention–I said half, he acknowledged I said half and then gave me a bib for the 10K, that I didn’t notice until we were starting. Talk about freaking out!! I was worried they would pull me off the half course or it wouldn’t count in my 50 state data. The course is HILLY. I live in the mountains but this was for real, hilly, down to the river (where it was much colder) and then back up out of the river bottoms. The course jumped off on to some trails that were really poorly maintained–broken concrete and gravel. Didn’t enjoy that at all. Could be crowded since the trail was narrow and it was an out and back so you had to put surges in to get around slower people. At the finish they had rolls from Pasta House (gross cold) and beer and water. No chocolate milk. I talked to the race people and it did get straightened out, so it did count as a half. I won my division and got a HUGE pumpkin pie. That was nice. Medal was good. Parking was plentiful and easy.
Great run other than being slightly long

This was a fun Halloween-themed run. They had us park at Six Flags and then take a bus to the race start. Mostly flat, easy course through the town of Eureka, MO. Course was extremely well-marked and there were a good amount of water stations and crowd support. Nice long-sleeved tech shirt and medal. Plenty of treats afterwards including donuts, beer, chips, bananas, and candy! Would definitely do this run again!
Very nice Halloween costume dress
Just one hill you do twice very subtle rolling to it other than that nice flat course. Good snacks at the end including donuts beer candy Fritos etc no alcohol … MORE
Just one hill you do twice very subtle rolling to it other than that nice flat course. Good snacks at the end including donuts beer candy Fritos etc no alcohol on course though.
Every year the coarse has more hills!

Plenty of parking near the start. I hate the start: all races start together, soon after the start we have a huge hill and the road is narrow. People are walking the hill and its hard to dodge them trying to keep a decent pace. On the half around mile 6.5 there is a huge hill, you go down and then back up and its steep! Once we get to the park its very flat. I like this race because its so close to my home, not many big races in the suburbs of St. Louis.

This was the race that gave me confidence to qualify for Boston. One hill at the beginning of the race. First prize in my age group got me a pumpkin pie. Parking was a nightmare.

I ran in 2020 so I can’t comment on what this race might be like in normal years. In 2020 the organizers had efficient protocols to keep runners spread apart. The swag was a sweatshirt hoodie which I wear around Halloween.
In 2020 we ran on trails on bike/hike paths. It was interesting and I think we passed a spot that Lewis and Clark used on their exploration. We also passed a nuclear water site. I certainly did not expect that.
Great views of St. Louis!

This was a lovely race, the weather was perfect, the course was pretty good as well. More rolling hills than I was expecting. Great course support, they really did a lovely job. Course announcements waited for the last person to finish, and were positive and enthusiastic the whole way.
