Having done the 5K in 2018, and not having done a 10K at all before, I knew that this was the race I wanted to make the leap at. I was dreading the hills from the 5K, but the course actually separated from the 5K course before the hills came (hospital hill to be specific). THe 10K course starts looking at the Western Auto building, next to Washington Square Park and heads down to 18th & Vine, then up Paseo to 27th St as you head down the long, gradual downhill past Liberty Memorial and to Union Station. 10/10 recommend.
