Springfield, IL

Springfield's running scene centers on flat, park-based courses through the state capital—the Orangetheory Fitness 5K and Illinois State Fair Parade Run are local staples on predictable terrain around 600 feet elevation. Cyclists dominate here via gravel: the Thunder Road Gravel Tour (96.56km) is the signature event, threading through central Illinois farmland with minimal elevation change, suiting gravel bikes and drop bars on hard-packed county roads. The Capital City Biathlon & 5K bridges both disciplines, attracting athletes who exploit the region's pancake-flat topography for speed work.
