The dry and mild climate of San Diego makes cycling a convenient and pleasant year-round option. The city has some segregated cycle facilities, particularly in newer developments, however the majority of road facilities specifically for bicycles are painted on regular roadways, covering over 1,570 miles throughout San Diego County. The city's hilly, canyoned terrain and long average trip distances—brought about by strict low-density zoning laws—somewhat restrict cycling for utilitarian purposes. In 2014 of.9% of commuters traveled by bicycle, below the average 1% for large U.S. cities. Also in 2014, San Diego experienced 6.8 bicyclist fatalities per 10,000 cyclist commuters, the average for all large cities was 4.7.
