A waitlist is used by the race director to manage the number of participants in their event. Most events have a capacity and when that capacity is reached, registration typically shuts down. With a waitlist, registration remains open, but registrants are added to a queue. Wait listers are not charged. If the director decides to let people in from the waitlist, each participant will be sent an email asking if they are still interested. If you answer yes, your card on file will be charged and you will be added. If you do not wish to participate, click no and you will not be charged. Directors control whether they intend to have a waitlist and control the selection process on their end.
