Mystic — The Hartford Marathon Foundation announced Tuesday that Hartford HealthCare will be the title sponsor of the 6th annual Mystic Half Marathon & 10K, which is slated for Sunday, May 17.

In addition, the foundation announced changes in the half-marathon course, including one that brings runners through Mystic Seaport Museum. The event, which attracts more than 2,000 runners each year, has raised $125,000 for the charitable efforts of the Rotary Club of Mystic since 2015.

Hartford HealthCare has been involved in other Hartford Marathon Foundation events, such as providing runner support services and managing the medical services teams at the annual Eversource Hartford Marathon in October.

Hartford HealthCare's involvement with the Mystic races come as it recently opened its Mystic Health Center on the former Perkins Farm property, which runners will pass during the race. Last year, Hartford Healthcare opened a facility on the site of the former Maple Breeze Park on Route 2 in Pawcatuck.

“Hartford HealthCare is a valuable partner and we’re excited to be expanding our relationship with them as we unveil this great new course in Mystic,” said Beth Shluger, CEO of Hartford Marathon Foundation.

The marathon foundation also announced that the half-marathon has been adjusted to provide fewer elevation gains in the second half of the course and runners now will finish in front of the new Milne Center for Ocean Science and Conservation at Mystic Aquarium.
