CARRABASSETT VALLEY — More than 1,500 runners from around the country are expected to gather at Sugarloaf for the 32nd Annual Sugarloaf Marathon and 15k on Sunday, May 18.

The marathon is Maine’s oldest continuously run marathon, and ranked one of the nation’s fastest, according to the Sugarloaf website.

In recent years, organizers have reported the highest number of registrants in the marathon’s history, and this year’s turnout is expected to surpass the record of 1,365 set in 2012.

As an official qualifying race for the Boston Marathon certified by the United States Track and Field Association, the Sugarloaf Marathon is popular among running enthusiasts. Despite its mountainous setting, the course is primarily flat or downhill, and ends with a gradual, 16-mile descent, the website said.

Marathon registration is $85; the Sugarloaf 15K registration is $43. There will be no on-site or day-of registration for either race. Registration will close May 5, or at 1,600 runners.

Interested runners should register online at www.sugarloaf.com/marathon.

All proceeds from the marathon will go to the Sugarloaf Region Charitable Trust, a private, nonprofit trust dedicated to improving the quality of life for the communities of the the Sugarloaf area. Last year, the marathon raised more than $12,000.

The top three men and women in each race receive cash prizes, and all entrants receive a T-shirt, post-race breakfast, massage, and a finisher’s medal. An all-you-can-eat pasta dinner will be served from 5 to 8 p.m. Saturday, May 17, in the King Pine Room in the Base Lodge.
