Deferrals allow a participant unable to attend this year’s event to defer their registration to the following year, space permitting. Deferrals are available for request up until Friday, February 24 (11:59 PM EST).
The deferral is applied only to the event in question – in this case, the Baptist Health 305 Half Marathon & 5K. Deferrals can only be applied to the same event the following year and cannot be carried over multiple years. Deferral processing fees and redemption deadlines apply.

If you would like to defer your entry to next year, please follow these instructions:

  1. Login to your ChronoTrack account
  2. Click “Change Race”
  3. Select “Defer my entry to another event”
  4. Follow steps to defer

Please note: A deferral fee of $30.00 will be administered at this time. Once you complete your purchase, you will be sent an email confirmation of your deferral status. You will be emailed instructions to register for the 2024 event after the 2023 event passes. You must follow these instructions to register for the 2024 event and follow deadlines – your registration will NOT automatically rollover.

*There are no deferral fee refunds under any circumstances.

Bib To Bib Transfer

You may officially transfer your race entry to another non-registered runner, space permitting. For further details and steps, see the instructions below.

Before you begin 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 currently registered runner will be charged a $30 transfer/deferral 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 the new registration is complete online.

How To Transfer Your Bib:

  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 will log-in to their ChronoTrack account, click “Change Race”, select “Defer my entry to another event”, then follow the steps to complete the deferral. A unique code will be auto-generated which may be used by the new runner to register for the event.
    • The currently registered athlete will be withdrawn from the event.
    • Once the registered athlete completes the deferral and pays the deferral fee, the unique code may be used by the new runner to register for the event at no additional cost.
    • Once the transaction is finalized, the transfer recipient will receive an email confirming race registration.
    • Once the transfer recipient completes the registration, the deferral will no longer be valid for the following year’s event.

Note: there is no guarantee a transfer may be made.

Any participant who transfers their 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. There are no transfer/deferral fee refunds under any circumstances.
