Half Marathon races near Pueblo

Pueblo Training Notes

Pueblo hosts 8 Half Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals run the Arkansas River Trail, the Riverwalk, Lake Runyon, and the levee when they want steady miles without overthinking it. Southern Colorado Runners Club keeps the week moving with a Monday 5K Beer Run/walk at Gold Dust Saloon and the Downtown Social Shuffle on Wednesdays. Pueblo Spring Runoff anchors the calendar as Pueblo's oldest and largest running event, with 5K, 10K, and 10M courses using the Arkansas River Trail. Pueblo's Firecracker 5K, Chile & Frijole Hot to Trot 5K & 10K, Colorado State Fair Stampede 5k, and Pueblo Levee Fun Run Walk fill in the race legs.

Locals ride Pueblo because the city has that unique mix of urban and rural characteristics that works for base miles, gravel, and open-sky Z2. Pueblo County gives riders more than 700 miles of unpaved roads, with high desert land south, Great Plains edges east, and the Rocky Mountains and Wet Mountains pulling the harder days west. The route covers 50 miles and gains 3175 feet, so it feels like real training, not a coffee spin. Active Pueblo - PACE gathers Thursday rides at Walter's Brewing Company downtown at 6:30 pm, and Pueblo Bike Riders roll 14-20 miles at a 12-15 mph pace. Grassroots Gravel, Farmstand 50, and Gravel Locos La Mediana are the anchor events.

May and October feel like the sweet spot, because most riders are out then and the heat has not pinned every interval to dawn. Summer stays hot and dry, and Pueblo sees 32.2°C or greater highs on average 71.6 days per year, so locals start early, carry more water, and keep Z2 honest. Winter usually stays mild enough for both sports, and snowfall often stays light and disappears after one or two days. Lake Pueblo and Cañon City aren't far from here and are usually rideable, but locals wait when trails are wet because the good dirt needs time to dry.
