With general registration at capacity, the only remaining entries to the Mystic Half Marathon & 10K are available through the new charity partner program. Fundraise a minimum of $500 for one of the three worthy local causes and your race registration will be free!
Details: You MUST use the links below to “Join the Team” to access charity registration. By registering for one of the limited availability charity entries, you agree to fundraise a minimum of $500 by May 31, 2025, and will be responsible for covering any difference in funds raised.
