Registration for 2022 opens

January 2nd, 2022 at 7:00 PM EST

NOTE: ADU reaches capacity incredibly quickly each year. To maintain the competitive integrity of the event, registration is FINAL under all circumstances. Please understand that there are absolutely no refunds, bib transfers or race deferrals for any reason. Once registration is closed on this site, there is absolutely no entry under any circumstances.

*A donation to a Rhode Island based non-profit of race management's choosing is embedded into registration each year. Thanks for supporting the beautiful place ADU calls home.

*As the three divisions become full, we'll activate the wait list. We believe in a wait list that is fair to our hopeful athletes. Therefore, the wait list is only open if we can calculate a 70% chance of our wait list participants getting into this year's race. If odds fall below 70%, we close the wait list down. If you sign up for a division that is wait listed, you will be notified by 3/1 of that given race year that you have or have not been invited into that year's ADU. If you have been invited, you will have 7 days to confirm your entry, and will then be charged at that time.
