Although we do not offer refunds or deferrals if you are unable to participate; you do have the option of transferring you entry to someone else.

Reminder: The transfer window will open on October 30. During this period, participants have the opportunity to transfer their marathon entry to another interested runner. To facilitate these transfers, we've created a dedicated Facebook group where runners can connect for these purposes. Additional information can be found here, and more details will also be included in upcoming newsletters.

Please note:  If you are thinking of transferring your marathon entry to the relay, the relay is on track to sell out this week.  Once the relay sells out, you will no longer have this transfer option.  If you intend to transfer to the relay, do so immediately here.
