We will update the challenge match results on Monday. Challenges for fourth are not a standard trackwrestling setup. I didn't think through the possibilities very well. We discovered that 5th could have beaten fourth earlier, that they could have wrestled each other twice splitting matches, and we had to adjust on the fly erroring on the side of mat time and let a match decide who would be in the top 4.
The hotel is the Adventureland Inn on the east side of Des Moines.
