Registration Changes

Distance Change

Need to change your race distance? Click here to go to your Chronotrack registration and select “Change Race” to choose a new distance. Please keep in mind that you will be prompted to pay for the difference in fees for upgrades, and will not be refunded the difference in fees for downgrades.

ALL CHANGES MUST BE COMPLETED/REQUESTED TWO WEEKS PRIOR TO THE EVENT, unless otherwise noted. All change requests after the deadline will need to be made in person at packet pick up.

Note:  Change requests are not guaranteed, are limited based on capacity of race at the time of your request and are first-come, first-serve.

Entry Deferral

Deferrals allow a participant unable to attend this year’s event to defer their registration to the following year. The deferral is applied only to the event in question and must be completed before the current year’s event date. There is a deferral fee of $30 for the half marathon and $10 for the 5K.

If you would like to defer your entry to next year, please login to your Chronotrack account, select “Change Race” and follow the instructions to “Defer my entry.”

Race Entry Transfer

If you are unable to participate in the 2019 305 Half Marathon & 5K, 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. 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.
  • The race entry recipient will be charged a $30 transfer fee to complete the transfer for the half marathon and $10 for the 5K.
  • A new bib will be assigned to the race entry recipient.

Race Entry Transfer Steps:

  • Find a non-registered runner interested in officially participating in the 2019 305 Half Marathon & 5K.  Race organizers do not participate in this part of the process.
  • To complete the transfer the registered runner must email FLevents@lt.life
    • 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    • You will be withdrawn from the event.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.
