Springfield, MO

Springfield's running is flat and road-focused across the Ozark plateau at 1,300m elevation, with the OMC Duathlon Series offering a mixed test of speed on local circuits. Cyclists dominate here: the Pancake Ride (99.8km) and FHT Iron Horse Gravel Grind (135.2km) draw serious riders into the rolling Ozark terrain south and east of the city, where gravel and dirt roads connect small towns and creek valleys.
