Half Marathon races near Davenport-Moline-Rock Island, IA-IL

Quad Cities Training Ground

Davenport-Moline-Rock Island, IA-IL hosts 6 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 Davenport river trail when they want flat miles, river air, and clean views of the Mississippi. Downtown Moline gives Run Club a steady long-run base, with Saturday routes starting at Mercado on Fifth for 5+ miles. Fleet Feet brings the structured side, and Cornbelt Running Club gives the scene its old-school backbone. Tempo Tuesdays meet at Bettendorf High School for 2, 3, 4, or 5 mile routes. The Davenport river trail runs 66 km and gains 66 m. The Quad Cities Marathon, Run the Rock 5K/10K, and Firecracker Run anchor the calendar.

Locals ride both sides of the river on the Mississippi River Trail, Great River Trail, Duck Creek bike path, and Arsenal Island. The bike paths cover both sides of the river and work well for Z2 base miles. Friends of Off Road Cycling keeps the dirt crowd pointed toward places like Sunderbruch Park, where sandy and rocky soil changes the feel fast. Quad Cities Criterium, Big River Gravel Series, and FORC-Side Thrill Ride give racers a crit, gravel, and trail target. The real climbs come as gentle rollers and bridge work, especially crossing the I-74 bridge.

September is the best month here, and the Quad Cities Marathon owns that late-season rhythm. Summer riding gets simple because bike rentals run April through November from downtown Davenport and downtown Moline. Summer Run Club shifts Long Run Saturdays to 7:00 AM from June through August, and the routes still include a 5K Course. The marathon can start cool, and one race morning sat at 55 degrees before temps reached the low 70s by the finish. Winter changes the mood for both sports, with runners leaning into steady base miles and cyclists choosing the paths, rollers, and off-road days that still make sense.
