An alley cat race is an informal bicycle race. Alley cats almost always take place in cities, and are often organized by bicycle messengers. The informality of the organization is matched by the emphasis on taking part, rather than simple competition. For instance, many alleycats present prizes for the last competitor to finish (sometimes known as Dead Fucking Last or DFL). The first race to be called an 'alley cat' was held in Toronto on 30 October 1989 and continued, in its original form, around Halloween and Valentine's Day for the following five years. In 1993, when Toronto messengers shared Alleycat stories at the first international messenger race (C.M.W.C Berlin), the name and the concept spread far and wide. Regularly organized Alleycats can be found in cities across North America, Europe and Asia. Many smaller cities with no cycle messenger population are also home to alleycats run by the burgeoning urban cyclist subculture.
Alley cats reflect the personality, contemporary environment and competitive interest of their organizer(s). Races may be extremely grueling and designed to eliminate all but the fastest and best overall messenger, or less competitive and designed to be enjoyed by the local messenger community around set holidays, such as NYC's July 4 Alleycat.
Substantiating the growth of alleycat racing is difficult, given the lack of publicity and record-keeping in the community. Some themes commonly associated with alleycats, such as the use of fixed-gear bicycles, became more popular in the later half of the 2000s. The number of alleycats being organized also appears to be on the rise, as non-couriers begin to organize their own races. Events featuring alleycat racing culture have seen significant expansion since 2000. Individual races have come to embrace issues important to messengers or messenger communities, such as New York City's 4/20:Hip to be Square, the Global Warming Alleycat held on the same day in Toronto, San Francisco, Mexico City, Berlin, and New York City, and Baltimore's GhettoBlaster. Meanwhile, events like the Bicycle Film Festival have expanded across dozens of cities and embraced many different expressions of alleycat-style bicycle culture. Alleycat veteran and videographer Lucas Brunelle is widely credited as having pioneered the art of filming alleycat races from the first-person perspective and sharing the footage online. YouTube currently hosts more than 1,000 videos of alleycat races, most of which have been uploaded since 2006.
Alleycats have occurred regularly in major cities all over the world and have expanded to smaller cities and towns over the last few years. As a result of the potentially dangerous nature of the sport as well as widely varying local laws an alleycat is almost never a fully legal endeavor.
In the United Kingdom, organised cycle racing on public roads requires the authority of the police and the relevant sporting organisation. However treasure hunts and time trials are legal.
Otherwise, organizers attempt to put issues of legality in the hands of racers. The decision to break any laws is left to the individual
On February 24, 2008, Matt Manger-Lynch was killed by a collision with a car while participating in the 'Tour Da Chicago', a winter alleycat series. Eyewitnesses reported that Mr. Manger-Lynch had failed to stop for a red light. His death prompted local news outlets to look closely at Alleycat races.
