Jacksonville, FL

Jacksonville's running is pancake-flat and humid, centered on riverside paths along the St Johns River and beach loops through Riverside and San Marco. The city hosts smaller 5K events like Run for the Pies and JWJ Bday 5K, but serious distance runners typically travel to cooler climates. Cyclists dominate here—the River City Summer Slam and 37th Endless Summer Watermelon Ride reflect Jacksonville's strength as a cycling hub, with 160km+ rides pushing south into the flat, fast coastal terrain where wind and heat are the only real obstacles.
