Awesome Games Done Quick (AGDQ) Schedules
This is a collection of schedules for speedrun marathons held by Speed Demos Archive (SDA):
Games Done Quick is a series of charity video game marathons. These events feature high-level play by speedrunners raising money for charity. Games Done Quick has teamed up with several charities in its five-year history, such as Doctors Without Borders and the Prevent Cancer Foundation.
The events held in the summer (SGDQ) are available under a different event, see Summer Games Done Quick.
CGDQ and JRDQ have been added here because they kind of are the ancestors of AGDQ in general.
