Race Entry Transfer

  • You will not be refunded/reimbursed for your original registration. Any transfer compensation must be arranged between you and the transfer recipient. 305 Half Marathon & 5K is 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.

  • Find a non-registered runner interested in officially participating in the 2018 305 Half Marathon & 5K.  Race organizers do not participate in this part of the process.
  • To complete the transfer the registered runner must email
    • You will need to provide 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    • You will be withdrawn from the event.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.


  • To complete the transfer in person at Packet Pickup:
    • The original recipient will need to first pick up their number at packet pickup.
    • Once the number is picked up, both the original recipient AND the transfer recipient must visit the solutions desk to transfer the number to the new recipient. The transfer recipient will be required to sign a participant waiver and pay the transfer fee.

305 Half Marathon & 5K reserves the right to disqualify race results for anyone who has transferred their bib without going through the official process.
