Maybe you’ve decided to go longer or shorter than the River Run distance you originally signed up for? You can make that change online within your Personal Event Profile.
To access your personal Event Profile for the River Run, log in with the email address you used during your race registration. (This will be the email address that you received your Confirmation Email with).
1. Find your race in the Events tab (1) under the Upcoming (2) section of your profile, then click on the blue Change Race button (3).
