Important Registration Changes in 2025

There is a new registration process for 2025. Registration will occur between March 1-31. If you have priority, you will receive an email with instructions on how to register. If you do not have priority, you must enter the lottery. 

ENTERING THE LOTTERY IS A TWO STEP PROCESS: 1. Register for the lottery group and pay the lottery entry fee, 2. Return to this page to register for your respective event and pre-authorize registration payment. You will not be charged for the race entry unless you win the lottery.

Priority racers will receive an email from RunSignup by 8AM on March 1 with a link to register and subject line “Reserved Entry for Mount Marathon”. If you don’t get an email and believe you have priority, check your spam, then contact director@mountmarathon.com if you need assistance.
