Most bike races are extremely serious and sanctioned by certain race organizations, says organizer Josh Kravetz. Basically what we try to do is to make the concept of cycling really fun, and ultimately what we want is to promote bike transportation so that people can incorporate it into their daily lives.
Post-race is Rio Grandes Fiesta de Bicicleta, a day-long bike party that celebrates all forms of cycling with both free and pay activities, including a road-bike drag race, a costumed cruiser ride and a messenger-style alleycat (whose first prize is a shiny new track bike). All games and contests are family-friendly.
The races start at Mile High Station, 2027 West Colfax Avenue; check-in begins at 7 a.m. Register at www.urban assaultrace.com or call Kravetz at 303-408-0747 for more info.
