Houston

Houston's race calendar centers on the Chevron Houston Marathon each January — Texas' largest running event, with roughly 27,000 runners across the full and half marathon combined on a flat, fast, Boston-qualifying course through downtown. The rest of the year fills in with a dense run of community 5Ks and 10Ks stretching from Sugar Land to Katy and Pearland, holiday-themed races like the Houston Holiday Series and Hot Chocolate Run, and the Women's Quarter Marathon each March. It's less a single marquee weekend than a marathon-anchored calendar with a race almost every week.
