SCHROON LAKE The 12th annual Adirondack Marathon Distance Festival is a sell-out. Sundays half-marathon and marathon relay are full, according to Joel Friedman of the organizing committee. The festival also includes the Adirondack Marathon, a 26.2-mile road race around Schroon Lake tomorrow as well as 5 and 10-kilometer road races in Chestertown today. Friedman said the half-marathon has 550 runners this year, while the two-person marathon relay has 100 runners. This is the first year for the relay. The marathon has more than 350 entrants, including six handcyclists, Friedman said, while nearly 300 runners are expected in the 5 and 10-kilometers races. The marathon has attracted runners from 35 states and three foreign countries. The marathon, 26 miles, 385 yards, will start at 9 a.m. on Main Street in Schroon Lake. The single loop course circumnavigates Schroon Lake over challenging forest roads with lakeside views until it finishes back at the Schroon Lake town beach. People who wish to walk the marathon course can get started at 7 a.m. The course will remain open until 3 p.m. The marathoners have company over the second half of the course as the half marathoners will toe the starting line in Adirondack at 10 a.m. to race to the finish in Schroon Lake 13.1 miles later. Marathon weekend begins today at 9:30 a.m. with 5 and 10-kilometer runs through the streets of Chestertown beginning and ending at the Chester Municipal Center. Also participating will be about 500 volunteers, who will man aid stations along the courses and work the finish area. Packet pick up for marathon and half marathon racers will be Saturday 11 a.m. to 5 p.m. at Schroon Lake Central School. There will be a running expo at the same time produced by Adirondack Sports & Fitness. At 4:30 p.m. the Strand Theatre in Schroon Lake will show the movie Spirit of the Marathon. There will be a pasta dinner, open to runners and others, that night at 5:30 at Word of Life. Tickets are available at the expo and at the door. To improve the spectator side of the event Taiko drummers (Japanese drums) will be playing in front of the Glens Falls National Bank from 11:15 a.m. to - 2 p.m., Friedman said. Wulaba drummers (North African drums) will be playing at three locations on the course and finishing from approximately 12:45 - 2:30 p.m. just below the intersection of Leland Avenue and Roue 9. Runners World magazine has selected the Adirondack Marathon as one of eight great events to kick off the fall racing season. The Adirondack Marathon is an official Team in Training (Leukemia & Lymphoma Society) fund-raising race, Friedman noted. Last year runners raised over $100,000 at the Adirondack Marathon. After this years race they will have raised in the range of one-half million dollars at the Adirondack Marathon. The Helpers Fund, a local charity for destitute families, partners with us and they organize and run the 5 & 10K, he added. The Adirondack Marathon has helped underwrite the event for the past 10 years benefiting The Helpers Fund with many thousand of dollars. New this year is our partnership with Team Hole in the Wall, Friedman said. They generate funds in support of the mission of Hole in the Wall Camps, the worlds largest family of camps for children with life-threatening diseases. The Adirondack Marathon also funds two annual $1,500 scholarships to graduating seniors in the local communities. Sponsors include Glens Falls National Bank, Grand Union Family Markets, Upstate Agency, Friedman Realty, Lake Placid/Essex County Visitors Bureau, Schroon Lake Chamber of Commerce, Stewarts, Asics, Schroon Lake Self Storage, Thrivent Financial for Lutherans, Southwoods, French Mountain Commons, Adirondax Service and Coca-Cola Enterprise.
