American running is enormous and fragmented. Six World Marathon Majors qualifiers (NYC, Boston, Chicago), thousands of half-marathons, the Spartan and OCR scene, and an ultra and trail calendar that includes Western States 100, Hardrock 100, JFK 50, and dozens of mountain hundreds. Cyclists range from urban gravel (Unbound Gravel in Kansas, Crusher in the Tushar in Utah) to mountain epics (Leadville Trail 100, Tour de Park City) to the road-racing legacies of Colorado, California and the Northeast. With over 400 metro areas in our calendar, scale is the defining feature of US endurance — there is always a race within an hour's drive, whatever the discipline.
