### Instruction: What does CMWCs stand for?
### Input: The Cycle Messenger World Championships, or CMWCs, are an annual urban cycling competition whereby cycle messengers and cycling enthusiasts showcase their skills in an array of events, many of which simulate everyday tasks for a cycle messenger. Each year, the CMWCs are held in a different city around the world, with each host city designing its own unique course. The highlight of the CMWCs is the main race in which cyclists are given manifests and must pickup and deliver items to various locations around the host city as quickly and efficiently as possible. The total number of pickups and deliveries, or "drop offs" is unknown to the messengers before the race, but has been known to reach up to 100 stops and usually takes between 3–4 hours to complete. The cyclist who completes all of the assigned deliveries in the least amount of time wins the race. In addition to the main race there are also several side events which have become increasingly popular over the past few years. These events change yearly depending on the discretion of the host city but usually include backward circles, bike polo, bunnyhop, cargo race, longest skid, sprints, and trackstand.
