The Poetry Marathon is an annual event that challenges participants to write 24 poems in 24 hour, posting the writing online via a shared Wordpress site. This year's marathon begins at 9 AM EDT on Saturday, August 13, 2016 and ends at 9 AM on Sunday. There is also a half marathon from 9 AM until 9 PM Saturday.

The Poetry Marathon is run (no pun intended) by Caitlin Jans (Thomson) and Jacob Jans, two writers and web publishers living in the Pacific Northwest. There is no charge to participate in the marathon, and in 2015, over 300 writers participated from nearly every continent but one (c'mon Antarctica!).

The Poetry Marathon website has an FAQ that answers the burning questions, like: How do I prepare for the Marathon? What if I can't be at a computer all day? What happens to the poems once I post them? and more. The site also features blog posts from previous participants who offer commentary on their marathon experience.

This year, the organizers plan to publish a Poetry Marathon Anthology of poems written during the marathon.
