Deferrals into the following year for the marathon are possible.  Please keep in mind that because we do allow deferrals, under no circumstances will a refund be granted.

All requests for deferral into the 2019 event must be made by email on or before February 18, 2018.   We are unable to grant exceptions.  

To accommodate your request, we will carryover your entry to the 41st annual Napa Valley Marathon to be held on Sunday, March 3, 2019.  

This is a one-time deferral and there is a $75.00 processing fee associated with deferring to the following year.

To request a deferral, please email
