The University of Okoboji Homecoming Races is a beloved annual event held every third Saturday in July in Arnolds Park, Iowa, set against the scenic backdrop of West Lake Okoboji and the Arnolds Park Amusement Park. The weekend offers a diverse suite of timed events—the Half Marathon, 10K, and 5K—that course along paved roads and trails around the lake, each offering shuttle service to start points and featuring finisher medals, age‑group awards, and cash prizes. Additionally, a competitive Triathlon (0.6 mile swim, 18 mile bike, 3.8 mile run) and Team Triathlon draw multisport athletes with rolling swim starts and transition zones at Preservation Plaza. The event, which began in 1978 by local organizers and has grown to host over 1,200 participants from across the U.S. and beyond, combines athletic challenge with community tradition and festival‑style celebrations.
