The Seacoast Half Marathon is one of the longest-running half marathons in coastal New Hampshire. We have made the difficult decision to make this year's race "virtual." That means you decide where to run or walk, and when (between October 31 and November 8. We've made this decision because it is the best way we can help to protect the health of our racers and our volunteers.  To make racing this year more interesting, we have added some options: You can choose a 5K, a quarter marathon (6.55 miles) or the half marathon. All racers will be able to download a personalized race bib, and a finisher's certificate after you post your finishing time. In addition, you can choose to get a long sleeve race shirt (5K and quarter half) or a l/s race shirt and a finisher's medal (half marathon). You can also choose a lower registration entry fee if you do not want the shirt or medal. The Seacoast Marathon is unique in that all of the revenue (after race expenses) goes to local non-profit beneficiaries. This year's beneficiary is Cornerstone VNA. So please make a donation to Cornerstone VNA when you register, and/or set up your own fundraising page to get family and friends help your fundraising efforts. You can use your donation/fundraising to earn free registration in the 2021 Seacoast half Marathon!
