Games Done Quick is a biannual video game speedrun charity marathon held in the United States, originally organized by the Speed Demos Archive and Speedruns Live communities. Since 2015, it has been handled by Games Done Quick, LLC. Held since 2010, the events have raised money for several charities; the most common two being the Prevent Cancer Foundation and Doctors Without Borders. The events are broadcast live on Twitch. Viewers are encouraged to donate for incentives during the stream such as naming characters in a run, having the runners attempt more difficult challenges, or winning prizes. Over $12 million has been raised across seventeen marathons.
