KEENE VALLEY — The Mountaineer gear store in Keene Valley will host its 13th annual Great Adirondack Trail Run on Saturday, offering both an arduous 11.5-mile run and a 3.5-mile fun run.

The longer run is at capacity, but registration remains open for the shorter distance. Cost for the 3.5-mile run is $20 per person, or $10 for kids 16 and under. The fun run goes from the Baxter Mountain Inn to the Mountaineer store, while the longer run goes up the backside of Hopkins Mountain and down into Keene Valley.

The run will be followed by food, live music and awards at the Keene Valley Country Club.

Tim Reynolds was the overall winner of last year’s race with a time of 1 hour, 38 minutes and 52 seconds. Saranac Lake resident Sarah Keyes won the women’s race in 1:48:59 and set the women’s record in the process.

Karl Schulz, of Lake Placid, won the 3.5-mile race last year in 23:22, while Aisha Young won the women’s race in 29:01.

The event is a fundraiser for both the Boquet and AuSable River associations, and participants are asked to bring a non-perishable food item for donation to the Keene Food Pantry.
