You may officially transfer your race entry to another non-registered runner. Before completing the transfer process, please note:

  • You will not be refunded/reimbursed for your original registration. Any transfer compensation must be arranged between you and the transfer recipient. The race organizers are not responsible for the terms of payment between parties in the transfer process and we do not condone the resale of registrations at elevated prices.
  • The race entry recipient will be charged a $30 transfer fee to complete the transfer for full and half marathon distances and $10 for any race distance less than a half marathon.
  • A new bib will be assigned to the race entry recipient only after new registration is complete online.

Race Entry Transfer Steps:

  1. Find a non-registered runner interested in officially participating in the said event. Race organizers do not participate in this part of the process.
  2. To complete the transfer, the registered runner must provide the race organizers with the name and email address of the person you are transferring your entry to.
    • You will be withdrawn from the event.
    • The transfer recipient will receive an email with a registration code. The transfer recipient is required to register with code, and pay the transfer fee.
    • Once the transaction is finalized, the transfer recipient will receive an email confirming race registration.
    • ALL TRANSFERS MUST BE COMPLETED/REQUESTED TWO WEEKS PRIOR TO THE EVENT. Contact our Athlete Services if you missed the deadline!

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.
