Pueblo, CO

Pueblo runs fast and flat along the Arkansas River levee system — the Pueblo Levee Fun Run and Colorado State Fair Stampede 5K both use the riverbank corridor, which stays near 1,450m elevation. Cyclists dominate the gravel and rural routes east and south of town; the Grassroots Gravel events (177km and shorter loops) and Farmstand 50 tap into the high plains grid roads and agricultural landscape that make southeastern Colorado a quiet alternative to Front Range crowds.
