If an event or registration option you want to attend is already filled, the button that was previously Register—on both the homepage and the event details page (and within registration for run groups)—turns to Join Waitlist.
To be added to the waitlist, click the Join Waitlist button. Then, once a spot opens up, you will be notified via email along with the other individuals on the waitlist.
If an event or registration option isn't full but you're unsure if you want to attend yet, we recommend you click the Watch button to get reminders to register when the event gets closer. Learn more about the watch feature here.
