Brownsville-Harlingen, TX

Running here is flat and hot—the Liberty at Sunrise 5K and Run to the Rescue are typical of the Rio Grande Valley's early-morning culture, where heat and humidity drive most efforts before 8am. Cyclists tackle the X-Pedition to Padre, a 51.5km time trial that crosses the causeway to South Padre Island through dead-flat coastal terrain, or head inland toward McAllen for longer road routes through citrus and agricultural country with virtually no elevation.
