Free Deferral Program: Athletes who register on or before January 14, 2024 are eligible to defer their 2024 race entry to the 2025 IRONMAN Chattanooga event free of charge. All deferral requests will be honored until 45 days before 2024 race day regardless of the reason for deferral. The deferral may only be used once. Athletes who elect to defer their entries forfeit any partial refund or insurance refund.

Payment Plan Option:  Athletes who register on or before January 14, 2024 may elect to pay via a three-part payment plan. Athletes will be charged the current Tier price in three equal installments. To elect the payment plan, an athlete needs to select payment plan at the checkout page during online registration. Please note after registering via the payment option plan, you will receive a receipt email for the first payment from Active. The confirmation email will only be sent after your third and final payment is received. All three payments must be completed for an athlete to race – partial payments will not be refunded or honored as race entries. Athletes electing the payment plan may also utilize the deferral option listed above as well as the fee-free transfer option and partial refund once all three payments have been completed.

If transferring from a higher priced race to a lower priced race, athletes will not receive a refund for the price difference.  We will make every effort to find a place at a race of the athlete’s choice, as long as the race has general entry availability. The deferral and transfer options may only be used once per each initial 2024 event registration.  Please note Relay entries are excluded from this offer. All transfer requests will be honored until 45 days before 2024 race day.
