Iowa City, IA

Iowa City's running scene centers on flat, fast courses along the Iowa River bottomland—the North Shore Distance Classic traces 21km through parks and green space on the north side, while downtown loops are popular for weekday training. Cyclists thrive in the rolling terrain radiating outward: the CRANDIC Time Trial Series uses flat 16.1km circuits, but serious gravel and road riders tackle the Core4 Gravel event's 193km route through Linn and Benton County roads, with steady 60–120m climbs typical of the region's agricultural landscape.
