What it is
For 24 hours, readers around the world read as much as they like and share their progress online: on Goodreads, Instagram, Reddit, Facebook, blogs and other apps. Through the day, the hosts post reading sprints, surveys and small challenges to keep everyone going.
It happens twice a year, in April and October. A blogger known as Dewey, of the blog The Hidden Side of a Leaf, held the first one in October 2007. She died in late 2008, and in 2009 the event was renamed in her honour (readathon history). A team of volunteer hosts runs it today.
How to take part
- Join the community. The organisers' Goodreads group is free to join and posts the updates and links for the day.
- Pick your stack. Choose more books than you think you need, with some short ones: novellas, comics, poetry or audiobooks keep you moving when you tire.
- Read any part of it. Nobody has to stay awake for 24 hours. Read for the hours that suit you and sleep when you need to.
- Share as you go. Post a photo of your stack at the start and an update every few hours.
Tips for a good readathon day
- Set out water, snacks and a charger before the start.
- Turn off notifications for everything except the readathon.
- Get up and walk for a few minutes every hour or two.
- Switch books when one drags. Finishing is not the goal; reading is.
