The processing fee is set in place by our registration providers, it’s how they make a living. The registration providers maintain registrations, and help out with the development of our system over time – they do great things for us and for you! We cannot waive processing fees.

We do not allow for paper, mailed, or faxed registrations, and even if we did we would still be required to include the processing fee.

You can log in to your registration to edit your personal registration information, excluding name, birthday, and gender. If you need to edit one of those categories, please email customer service.

The deadline to make changes to your personal registration information is Friday, August 28, 2026.

To update your email address, phone number, or mailing address you will select ‘Participant Info’ in the white menu bar. To update your emergency contact you will select ‘Questions’ in the grey menu bar. To update your shirt size you will select ‘Add-Ons’ in the grey menu bar.

Yes, you may upgrade or downgrade your race distance as long as the field is not filled. If the entry fee for your new race is less than originally paid, there will be no refund of the registration fee.

To take advantage of this offer please log into RunSignUp and Click Here to manage your registration. Select the transfer registration option to switch your race level and process the upgrade fee if applicable.

The deadline to switch your race level online is Friday, August 18. (After this date, upgrades and downgrades can be processed at packet pick-up.)

This event may be cancelled or postponed due to circumstances beyond the control of Corrigan Sports Enterprises, Inc.  Inclement weather, or emergencies such as public safety, public health concerns or municipal directives, can impact the implementation of a race.  Public safety measures such as these may cause Corrigan Sports Enterprises to cancel or postpone this event.
