You may officially transfer your race entry to another non-registered runner. Transferring is a paid participant finding a second runner to take over their race spot. The Miami Marathon has enabled online Runner to Runner Bib Transfers available through January 16, 2021.

The Transfer to Another Runner option can be found by logging on to RunSignup, navigating to your Profile > Upcoming Events > Manage Registration > Transfer to Another Runner.

On the Transfer to Another Runner page, you will see your transfer Information, please confirm that the information is correct: registration number, your name, and event. (Please note that the recipient can only register for the event distance that is being transferred to them.)
After reviewing the Transfer information, you will enter the Recipient First Name, Last Name, and Email address and note the only transfer offer choice is Registration Gift Transfer which incurs a $30 Transfer Fee to be paid by the recipient.  The recipient will receive an email notification with a unique link which they must use to claim this transfer, pay the $30 fee, and complete their online entry.

NOTE: Life Time Miami Marathon does not assist registrants in finding transfer candidates. Any financial transactions involved in registration transfers are strictly between the immediate parties and are not the responsibility of Life Time Miami Marathon (Transfer at your own risk!)

Any participant who transfers his or her race entry or race bib without following the above process will be removed from official race results and disqualified from participating in any future Life Time event.

Note: This policy is strictly available for race entry only. This policy does not apply to add-on packages.
