St Charles County, Missouri will host this USA Qualifier on the 9,000 sq m (30,000 sq ft) Velosolutions Pump Track that features a skills section for every level of rider. There’s a beginner loop that’s separate from the other lines, an intermediate main course with a circuit of rollers, banked turns and two 21m (70ft) quads, while the expert rhythm section is a series of six jumps that vary in height. The largest in the jump line is 2.4m (8ft) tall.
