People around the country are dusting off their helmets and turning to a two-wheeled commute to work more than ever, and D.C. is predictably among the cities leading the charge.

Between 2009 and 2013, the number of workers in the Washington area commuting by bike jumped from 14,737 to 20,894, according to Census Bureau numbers analyzed by SelfStorage’s Moving Blog. That puts the five year growth rate at 41.78 percent. It also makes D.C.—long ranked one of the most bikeable cities in America—seventh among the country’s top 100 metro areas in terms of bike commuting growth.

Charleston topped the list with a 73 percent growth rate, though they were starting from a much smaller place (going from 1,588 bike commuters in 2009 to 2,753 in 2013), followed by Ogden, Utah and Fort Myers, Florida.
