Grab your sneakers and support Cornerstone VNA!

The Seacoast Half Marathon is one of the longest-running half marathons in coastal New Hampshire. The race is unique in that all of the revenue (after race expenses) goes to local non-profit beneficiaries.

Traditionally the Seacoast Half Marathon selects a new non-profit beneficiary each year, but this year is different! Since the 2020 SHM transitioned to a virtual event due to COVID-19, and did not produce the same level of fundraising for Cornerstone VNA, the 2020 beneficiary, the SHM Race Committee has decided to continue with Cornerstone VNA as the 2021 beneficiary.

Cornerstone VNA is pleased that the SHM has chosen to support those on the front lines of this pandemic again for 2021!


You can register for the in-person Seacoast Half Marathon on October 31, or you can choose from one of several virtual distance options and run a 5k, Quarter Marathon or Half Marathon from October 23-October 31.

When you register online for the Seacoast Half Marathon, a registration confirmation email is sent to you automatically. If you believe that you registered online, but you did not receive a confirmation and/or do not see your name on this roster, please click here to receive a duplicate confirmation. If you do not receive a confirmation shortly after you enter the information requested and click the SUBMIT button, it is quite likely that you did not complete your registration for this race. You can double-check by contacting your bank to see if they show a race registration charge on your credit card.

“The field is now capped at 1,400, and continues to be a ‘must’ on the schedules of local runners.”
