The Pregnancy Entry Deferral request period for the 2025 race is March 1-July 31, 2025.

Racers who are unable to run the Mount Marathon Race due to pregnancy or childbirth may request a race deferral in order to retain their Priority Registration status for the next year. This deferral is not available to the partner of someone who is pregnant.

Who Is Eligible to Use the Pregnancy Entry Deferral?

• A person who is registered for AND has paid the full entry fee for that year’s race AND has a pregnancy or recent childbirth related reason to defer – regardless of how they obtained their race entry (Priority, lottery, earned entry, sponsor bib, etc.)

To obtain a Pregnancy Entry Deferral, a race entrant must:

• Submit a Pregnancy Deferral Request Form below by July 31 AND upload a written confirmation of the pregnancy or proof of child’s birth that is signed by a medical professional.

NOTE: Approved deferrals will receive an invitation to register the following year from March 1-31 using the normal registration process; they must still pay the entry fee for the following year.

APPLY EARLY IF POSSIBLE: If you are aware of your pregnancy in March, please submit your pregnancy deferral form by March 31. That way your priority status is retained for the following year, but your spot can be made available through the lottery for another woman to race in the current year. If you apply after April 1, the pregnancy deferral will be approved but your spot will go unused for that year’s race.
